Question

solve the system of equation by using the addition method or substitution method
y=x-5
y=11-7x

Answer 1

Given that y = both of the x expressions in the two equations, you can put that x - 5 = 11 - 7x. Then just simplify and so on, to get 8x = 16, which gives you x = 2.

Answer 2

How did you get 8x=16

Answer 3

By adding 7x to the left side and adding 5 to the right side to even out the equation and combine like terms.
