Question

Solve -18+x=-3
A. -15
B. 15
C. 21
D. -21
I need the answer​

Answer 1

Answer:
`x=15`

Move all terms containing x to the left, all other terms to the right

Add 18 to each side of the equation

`-18 + 18 + x = -3 + 18`

Combine like terms: -18 + 18 = 0

`0 + x = -3 + 18\\x = -3 + 18`

Combine like terms: -3 + 18 = 15

`x=15`

Answer 2

B. 15 because
-18+x=-3
X= -3 + 18
X = 15
