1 fill in the blank 0 points
7m - 4 - 9m - 36 = 0
m = type your answer...
2 fill in the blank 0 points
-2 = -5t + 10 + 2t
t = type your answer...
3 fill in the blank 0 points
10(5 - n) - 1 = 29
n = type your answer...

Explanation:

Step1: Combine like terms for m

$7m - 9m - 4 - 36 = 0$
$-2m - 40 = 0$

Step2: Isolate term with m

$-2m = 40$

Step3: Solve for m

$m = \frac{40}{-2} = -20$

Step1: Combine like terms for t

$-2 = -5t + 2t + 10$
$-2 = -3t + 10$

Step2: Isolate term with t

$-3t = -2 - 10$
$-3t = -12$

Step3: Solve for t

$t = \frac{-12}{-3} = 4$

Step1: Expand the parentheses

$50 - 10n - 1 = 29$
$49 - 10n = 29$

Step2: Isolate term with n

$-10n = 29 - 49$
$-10n = -20$

Step3: Solve for n

$n = \frac{-20}{-10} = 2$

Answer:

$m = -20$
$t = 4$
$n = 2$
