Please help to solve to find x,y

1. y=7x-3

2. 4x+2y=8

Take the value of y in the first formula and substitute it for y in the second formula. Solve the second formula for x.

Once x is found, solve for y in the second formula. Check by inserting both values into the first formula.

I hope this helps. Thanksfor asking.

1.y=4 x=1

2.x=1 y=2
