Answer 4

Can you help me break down how you did that?

Answer 5

-2(t-7)-(t+5)=5

simplify the equation first.

MDAS rule applies here..

for -2(t-7):

-2t+14

for -(t+5):

-t+5

combine the two equations..

-2t+14-t+5=5

now you can solve for t by combining in like terms.

-3t+19=5

add both sides by -19 to eliminate the +19..

-3t=5-19

-3t=-14

divide both sides by -3 to eliminate -3

\[t = -14/-3\]
