Solve: We'll use substitution. After moving -2*y to the right, we get: , or . Substitute that
into another equation: and simplify: So, we know that y=1. Since , x=4.
Hi
using substitution to solve
x=2y+2
2x+3y=11
substituting (2y+3) for x
2(2y+2) + 3y = 11
solving for y
4y + 4 + 3y = 11
7y = 7
y = 1 and
x = 4 | x = 2y + 2= 2*1+2 = 4
One solution (4,1)
