Question

Can someone please help me? And it says “Solve each equation. Then, prove that your answer solves the original equation?

Answer 1

Step-by-step explanation:

We need to solve each equation.

a. 6c = 30

c = 30/6 = 5

b.

2d-6=12

Adding 6 both sides

2d-6+6=12+6

2d = 18

d = 9

c.

$\dfrac{x}{3}+9=2\\\\\dfrac{x}{3}=-7\\\\x=-21$

d.

50=14+3m

50-14=3m

36=3m

m = 12

Hence, this is the required solution.
