To solve for "x" 8x+10y=12 -10y -10y Subtract 10y from each side 10y-10y gives you 0; then you have 12-10y 8x=12-10y 8x/8x = 12/8 -10y/8 Then you divide all the numbers by "x" x=1.5 - 1.5y
To find "y" 8x+10y=12 -8x -8x You want to first subtract x from both sides. 10y=12-8x 10y/10=12/10 -8/10 Then divide all numbers by 10. y=1.2 -0.8y
