Answer:
x = 43/12
y = - 35/6
Step-by-step explanation:
4x + 4y = -9
y = 2x - 13
4x + 4(2x - 13) = - 9
4x + 8x - 52 = - 9
12x = 52 - 9
12x = 43
x = 43/12
y = 2×43/12 - 13
y = 86/12 - ¹²⁾13
y = (86 - 156)/12
y = - 70/12
y = - 35/6
You add the numerators and keep it over the denominator. 4/16 plus 12/16 is 16/16 and when the same number is the denominator and numerator at the same time, its 1
