The solution to which system of equations has a positive x value? a.) x + y = 0
3x - y = 2

b.) 3 - y = 2
y = -x - 2

c.)x + y = 0
3x - 3y = -6

d.)y = -x - 2
x + y = 0

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?
