Question

(Please I will mark BRAINLIEST, not lie)Use this equation to solve for the missing variable:

Answer 1

Y = 8x + 12

if x = -6

y = 8(-6) + 12

y = -48 + 12

y = - 36


if y = 13

13 = 8x + 12

13-12 = 8x

8x = 1

x = ¹/₈ ≈ 0.125

Answer 2

Answer:

If x = -6, y = -36

If y = 13, x = $\frac{1}{8}$

Step-by-step explanation:

There is one equation and are asked to find x and y if there is a certain value to substitute either x or y.

Let's start with x, we know that x = -6. Meaning that we need to subtitute x for -6. Do as followed :

y = 8(-6) + 12

y = -48 + 12

y = -36

Now do y, we know that y is 13. Meaning that we need to substitute y for 13. Do as followed :

8x + 12 = 13

We need to isolate x alone, so do as followed :

Subtract 12 from both sides to get 8x alone :

8x = 1

Divide 8 from both sides to get x alone :

x = 1/8
