2) subtract the two equations to erase the y value (since 2y2y=0) and solve for x, then add them to erase the x value (since 3x+3x=0) and solve for y. ur x values should be 8.5 and 7.5 respectively. i don't know how to do #1
step by srep the problems
1) x+ y=13
22x + 36y =356
2)3x +2y=8
3x + 2y=8
#1 use substitution. subsitute y with y=13X, and solve for x.
22X+36(13X)=356
14X=112
x=8
8+y=13
y=5
