x + 2y = 7

3x- 2y = -3

Answer 1

@robz8

Answer 2

same thing as before, except the y coefficients are already the same for you

Answer 3

so just add the equations together

x+2y=7
+3x-2y=-3

=4x = 4

x = 1

just like before, plug x back into one of the equations and solve for the value of y

(1) + 2y = 7

Answer 4

thx again
