A pair of equations is shown below: y = 6x + 9 y = 7x + 7 What is the solution to the pair of equations?

x=2, y = 21

Step-by-step explanation:

y = 6x + 9

y = 7x + 7

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

6x+9 = 7x+7

Subtract 6x from each side

6x+9-6x = 7x - 6x+7

9 = x+7

Subtract 7 from each side

9-7 = x+7-7

x=2

Now we need to find y

y = 6x+9

y = 6 (2) + 9

y = 12 + 9

y = 21
