You need two independent equations to get unique values for x and y.
the problem asks if (1,-6) is a solution to this equation and this is all it gives me
Well that is a help!
9x+8y=11 for x and y
9(1) +8(-6) = 11 ? or not?
9 - 48 = 11 ? NO WAY
Algebra 1 - 9x-8y=42 4x+8y=-16
algebra - solve by substitution method 9x+7y=-23 x=48-8y
algebra - use linear combinations to solve these system. 3x+2y=22 9x-8y=-4
algebra - solve system by substitution 9x-3x=3 3x+8y=-17
Algebra - Solve by the substitution method 9x+8y=-5 x=40-9y The solution is ...
