Best Answer

From first equation: x = 39 - 7y

Substitute this in second equation: 3(39 - 7y) - 2y = 2

ie 117 - 21y - 2y = 2

ie 115 = 23y

ie y = 5, making x = 4.

Solve this equation using subtitution 8x subtract y equals 4 and 5x plus 3y equals 17?

y=4x=1Because:8x - y = 45x + 3y = 17You can rearrange the first equation to give:y = 8x - 4And substitute this into the second equation:5x + 3(8x - 4) = 17Expanded out:5x + 24x - 12 = 1729x - 12= 1729x = 29So x=1And because you know know x you can put that into an equation to find y:y = 8x - 4y= 8 - 4y= 4
