Answer:
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
