How do I do this problem using the substitution method. x - 9y = -66, -x - 5y = -46

X -9Y = -66

-X -5Y = -46 Solve one the the variables in terms of other, and substitute in the other equation.

and becomes equation with one variable/

X = 46 - 5Y from 2nd equation.

46 - 5 Y - 9Y = -66

66 + 46 = 14 Y

112 = 14 Y

Y = 112/ 14 = 8

Substitute back into 1st equation:

X = 46 - 5(8) = 8

X = 6
