Question

-8(t-8) -(t+1)=9

Answer 1

-8(t-8) - (t+1) = 9

Distribute the -8 to the elements in the parentheses.

(-8t + 64) - (t +1) = 9

Lose the parentheses. Don't forget to distribute the -1 to the second set of parentheses.

-8t + 64 - t - 1 = 9

Combine like terms.

-9t + 63 = 9

Move non t's to the right side of the equation by subtracting 63 from each side.

-9t + 63 - 63 = 9 - 63
-9t = -54

Divide both sides by -9.

t = 6
