Question

Solve the system, using substitution. What is the x coordinate of the solution?

x = 2y - 2 and 3x - y = 14
A. 6
B. 4
C. 1
D. 0
E. no solution

Answer 1

So, since x equals 2y -2 put that as x in the other equation.
3(2y -2) -y =14 Then just solve! Now you only have one variable to work with!

Answer 2

B?

Answer 3

Yes! Distribute the 3 --> 6y - 6 - y = 14 --> 5y - 6 = 14 --> 5y = 20 --> y = 4

Answer 4

Thank you so much you are such a help!

Answer 5

No problem at all :)
