Question

What is the solution to this equation?
X
- 12 = -4
O A. x = -8
O.B. x= 8
O c. x= 16
O D. x= -16

Answer 1

Answer:

$\large \boxed{\text{B. x = 8}}$

Step-by-step explanation:

$\begin{array}{rcll}x - 12 & = & -4 & \\x - 12 + 12 &= & -4 + 12 & \text{Added 12 to each side}\\x & = & \mathbf{8} & \text{Simplified}\\\end{array}\\\large \boxed{\mathbf{x = 8}}$

Check:

$\begin{array}{rcl}8 - 12 & = & -4\\-4 & = &-4\\\end{array}$

OK.
