Can you work this problem out for me 7t-5=10t+8-4t?

Question

Need the problem solved

Answer 1

Taking all the t's to one side of the equation, and the numbers to the other side:

7t - 10t + 4t = 8 + 5 ***; so that 11t - 10t = 13, or t = 13.

Check this solution back in the original equation:

7 t - 5 = 91 - 5 = 86, while 10t + 8 - 4t = 130 +8 - 52 = 138 - 52 = 86. Good!

Both sides, evaluated with t = 13, are equal, confirming that t = 13 is the solution.


*** Notice that when a "+" sign is "carried across the '=' sign,' it becomes a "-" sign. Conversely, a "-" sign carried across becomes a "+" sign. That's the key to dealing with simple equations like this. Do try it for yourself next time, and remember to check your answer, also, at the end.

Good Luck!

Live long and prosper.

Answer 2

7t - 5 = 10t + 8 - 4t
subtracting 10t from both side of the equation gives
7t - 10t - 5 = 8 - 4t
adding 4t to both sides of the equation gives
7t + 4t -10t - 5 = 8
adding 5 to both sides of the equation gives
7t + 4t - 10t = 8 + 5
adding the t's gives
1t = 8 + 5
which gives
1t = 13
But 1t is the same as writing "t" mathematically or 1 X t, therefore
t = 13

QED

Answer 3

7t-5=10t+8-4t?
7t - 10t + 4t = 8 + 5
t = 13
<>>

Answer 4

7t-5=10t+8-4t
-4t -4t
7t-5=6t+8
+5 +5
7t=6t+13
-6t -6t
t=13

Answer 5

7t-5=10t+8-4t First, combine all like terms.

-5-8 = -7t + 10t -4t

-13 = -t

13 = t

Answer 6

t = 13

Answer 7

t=13

Answer 8

7t = 6t + 8 + 5
t = 13

Answer 9

if you are solving for t then here it is

7t - 5 = 6t + 8 just combine like terms
t - 5 = 8 subtract 6t from both sides
t = 13 then add 5 to both sides and you get what t is equal to
