Please help to solve to find x,y
1. y=7x3
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

x=7/9
y=22/9
