How do you do this problem: 6(3x-5)-7x=25?????

Question

Oh, and also, how do you do this one too: -2(5+6m)+16=-90? Please help, and if you ca, may you please show the work too, thank you sooooooooooooooo much!!!!! I luv you all!!!

Answer 1

6(3x - 5) - 7x = 25
18x - 30 - 7x = 25
18x - 7x = 25 + 30
11x = 55
x = 55/11
x = 5

------------------------------------------------------------------------------------

-2(5 + 6m) + 16 = -90
-10 - 12m + 16 = -90
-12m = -90 + 10 -16
-12m = -96
m = (-96)/(-12)
m = 8

-Good Luck-

Answer 2

6(3x-5)-7x=25
6*3x - 8*5 - 7x=25
18x-30-7x=25
18x - 7x - 30=25
11x-30=25
11x-30 + 30 = 25+30
11x=55
11x / 11 = 55 / 11
x=5
thus (checking answer)
6(3*5-5)-7*5=25 --> 6(10)-35=25 --> 60-35=25 --> 25=25 (check)

and the other

-2(5+6m)+16=-90
-2*5 + 6m +16 = -90
-10+6m+16=-90
-10 + 16 + 6m= -90
6+6m=-90
6 - 6 + 6m= -90 - 6
6m=-96
6m / 6 = -96 / 6
m=-16

thus
-2(5+6*-16)+16=-90 --> -2*5+-96+16=-90 --> -10+-96+16=-90 --> -106+16=-90 --> -90=-90 (correct!)

Im really los on how i got -16 and everyone else got 8... but for some reason it still checks out... weird

Answer 3

OK this is easy,

for the first one you distribute the 6 to the 3x and the -5
then you combine like terms
then you get rid of the 30 by adding to both sides
then you divide by 11 to get the final answer which is x=5
6(3x-5)-7x=25
18x-30-7x=25
11x-30=25
11x=55
x=5

on this one you do the same thing but with different numbers
-2(5+6m)+16=-90
-10-12m+16=-90
6-12m=-90
-12m=-96
m=8

Answer 4

The first one:

6(3x-5)-7x=25
18x-30-7x=25
11x-30=25
11x=25+30
11x=55
x=55/11
x=5


The second one:

-2(5+6m)+16= -90
-10 -12m+16= -90
-12m+6= -90
-12m= -90-6
-12m= -96
m= -96/-12
m= 8

Answer 5

1. 6(3x-5)-7x=25 18x-30 -7x =25 11x-30 =25 11x=25+30
11x = 55 x=5

2. -2(5+6m)+16 =-90 -10 - 12m+16 = -90 -12m+6 = - 90
-12m = -96 m=8

Answer 6

Problem 1:
6(3x-5)-7x=25
18x-30-7x=25
11x-30=25
11x=55
x=5

Problem 2:
-2(5+6m)+16=-90
-10-12m+16=-90
6-12m=-90
-12m=-96
m= 8

Answer 7

6(3x-5)-7x = 25
18x-30-7x = 25
11x = 55
x = 5

-2(5+6m)+16 = -90
-10-12m+16 = -90
-12m = -96
m = 8

Answer 8

6(3x-5)-7x=25
(18x-30)-7x=25
11x=25+30
11x=55
x= 5


-2(5+6m)+16= -90
-10-12m+16= -90
-12m+6 = -90
-12m = -96
m= -96/-12
m=8

Answer 9

6(3x-5)-7x=25
6*3x-6*5-7x=25
18x-30-7x=25
18x-7x=25+30
11x=55
x=55/11
x=5
...................................
Now,we have to solve:
-2(5+6m)+16= -90
-2*5+(-2*6m)+16= -90
- 10 - 12m +16 = -90
Multiply both sides by minus sign, we will get
10+12m- 16=90
12m=90-10 + 16
12m=80+16
12m=96
m=96/12
m=8

Answer 10

18x-30-7x=25
=>11x=55
so x=5


-10-12m+16=-90
-12m=-96
=>m=8
