What is your answer?

Answer 6

Show your steps then I point out where you may went wrong

Answer 7

I got (–10, –40)

Answer 8

the 10 is right but should be positive value.

y = 3x + 10
y= 4x

Since y is isolated for both equations you substitute

4x = 3x + 10

Solve for x

4x - 3x = 3x + 10 -3x

x = 10
