Question

Use addition to solve the linear system of equations.

y = -3x + 1
y = 2x - 4

Please show me step-by-step, I'm having a very hard time with this and I'm behind on work

Answer 1

since both equal y, they have to equal each other. set them equal to each other as -3x+1=2x-4. add four to both sides to get -3x+5=2x. add -3x to both sides to get 5=5x. divide both sides by one to get x=1.
