solve each system of equations using substitution.

-2x + y = 2...Equation A -x + 3y = -4..Equation B I will solve Equation A for y. y = 2x + 2 I will now plug 2x + 2 for y in Equation B to find the value of x. -x + 3(2x + 2) = -4 -x + 6x + 6 = -4 5x = -6 - 4 5x = -10 x = -10/5 x = -2 To find the value of y, replace x with -2 in EITHER given equation. -2x + y = 2 -2(-2) + y = 2 4 + y = 2 y = 2 - 4 y = -2 The answer is x = -2 and y = -2 which can be written as a point (-2,-2). fdr84@hotmail.com
