Question

Solving Equations Reminder need to show ALL work **Number 1

Answer 1

1.I WILL USE CROSS MULTIPLICATION

`( - n)/(4) = 13 \\ - n = 13(4) \\ - n = 52 \\ ( - n)/( - 1) = (52)/( - 1) \\ n = - 52`

2.

`(3x)/(4) - 5 = 4 \\ (3x)/(4) (4) - 5(4) = 4(4) \\ 3x - 20 = 16 \\ 3x = 16 + 20 \\ 3x = 36 \\ (3x)/(3) = (36)/(3) \\ x = 12`

ATTACHED IS THE SOLUTION.
