Respuesta :
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
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:
If x = -6, y = -36
If y = 13, x = [tex]\frac{1}{8}[/tex]
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
