Question

I need some help with this math​

Answer 1

(-3, -10)

Explanation:

y = 6x + 8

y = x - 7

6x + 8 = x - 7

take an x from both sides 5x +8 = -7

take 8 from both sides 5x = -15

divide both sides by 5 x = -3

plug in the x 6 (-3) + 8 = y

-18 + 8 = -10

x = -3

y = -10

Answer 2

(-3,-10)

Explanation:

y = 6x+8

y = x-7

Since both equations are equal to y, we can set them equal to each other

6x+8 = x-7

Subtract x from each side

6x+8 -x = x-7-x

5x +8 = -7

Subtract 8 from each side

5x+8-8 = -7-8

5x = -15

Divide each side by 5

5x/5 = -15/5

x = -3

Now we need to find y

y =x-7

y = -3-7

y = -10
