Solve. 3(x – 5) + 3x = 4x + 5?

Answer 1

Subtract 3x from both sides. You now have: 3(x - 5) = x + 5. Distribute the 3 to get 3x - 15 = x + 5. Subtract x from both sides and add 15 to both sides to come up with 2x = 20. Divide by 2 to end up with x = 10.

Answer 2

The first thing you want to do is multiply the parentheses to get {3x - 15 + 3x = 4x + 5 }. Then you want to get the x's by themselves and then normal numbers on the other side. which if you add {3x + 3x - 4} it equals 2x. And on the other side you would get {5 + 15} equals 20. so now your equation looks like this {2x = 20}. And 2 multiplied by 5 = 10

Your answer is: 10

Answer 3

x= 10

Answer 4

x=10

Answer 5

3 (x-5) + 3x = 4x + 5
multiply (x-5) by 3
3x-15 +3x = 4x + 5
add like terms
6x - 15 = 4x + 5
subtract 4x on both sides
2x - 15 = 5
add 15 to both sides
2x = 20
divide 2 into 20
x= 10

Answer 6

3(x-5) +3x = 4x + 5
Simplify by using the distributive property in the parentheses:
3x - 15 + 3x = 4x + 5
Combine the 3x and 3x:
6x - 15 = 4x + 5
Subtract 4x from both sides:
2x - 15 = 5
Add 15 to each side:
2x = 20
Divide by 2:
x = 10!

Answer 7

x=10

Answer 8

x=10

Answer 9

USE YOUR GRAPHING CALCULATOR!

You can go to Y=and type 3(x – 5) + 3x

go to the second Yand type=4x + 5

Next, go to 2nd (yellow key usually) and press graph. Look at the table. If the two Y columns have the same number, (any number but they must be the same) The value under the x is the answer.

Answer 10

3x-3*5=3x-15------------1
ie3x-15+3x=4x+5
add x values in left side,so 6x-15
6x-15=4x+5
now bring the x values together on any side but be careful in signs(+ or -)
6x-4x=5+15
2x=20
so x=? 20/2 =10 (solved)
Now u can also cross check ur answer by applying the x value in the question.
