Question

Solve system of linear equations which is y=4x+6
And y=2x+2

Answer 1

so you can subsitute and make each equation equal to the other
4x+6=2x+2
subtract 2x form boht sides
2x+6=2
subtract 6 form both sides
2x=-4
sivide by 2
x=-2
subsitute
y=2(-2)+2
y=-4+2
y=-2

the solution is x=-2 y=-2

Answer 2

`\left \{ {{y=4x+6} \atop {y=2x+2}} \right.\\\\ Equal\ both\ equation\\\\ 4x+6=2x+2\ \ | subtract\ 2x\\\\ 2x+6=2\ \ \ | subtract\ 6\\\\ 2x=-4\ \ \ | divide\ by\ 2\\\\ x=-2\\\\ y=2x+2=2*(-2)+2=-4+2=-2`
