Solve for substitution 8x+2y=13 and 4x+y=11

Solving for X:

1) y=-8x+6.5 y=-4x+11

2) - 8x+6.5=-4x+11

3) - 8x=-4x+11-6.5 (Subtract 6.5 from both sides)

4) - 8x+4x=11-6.5 (Add 4x to both sides)

5) - 4x=4.5

5) x=-1.125

Solving for Y:

y=-8 (-1.125) + 6.5

y=9+6.5

y=15.5

y=-4 (-1.125) + 11

y=4.5+11

y=15.5

x=-1.125

y=15.5

or

(-1.125,15.5)
