Y-2x=8
y=8+2x
2y+x=1
2*(8+2x)+x=1
x=-3
y=2
so the answer is x=-3, y=2.
y=8+2x
2y+x=1
2*(8+2x)+x=1
x=-3
y=2
so the answer is x=-3, y=2.
How Do I Solve 2y+x=1, Y-2x=8 By Using Substitution?
2y+x=1, y-2x=8.
X=1-2y,y-2*(1-2y)=8,y-2+4y=8,5y=10,y=2;
x=1-2*2=-3.So x=-3,y=2.
X=1-2y,y-2*(1-2y)=8,y-2+4y=8,5y=10,y=2;
x=1-2*2=-3.So x=-3,y=2.
