Answer:
x = 9
Step-by-step explanation:
-5(1 + 1x) = -50
-5 + -5x = -50
-5 + -5x + 5 = -5x
-50 + 5 = -45
-5x = -45
-5x / -5 = x
-45 / -5 = 9
x = 9

Answer:
x = 19, y = -5
Step-by-step explanation:
x + y = 14 => x= 14-y
2x + 4y = 18 => 2(x+2y)=18 => x+2y=9
x+2y=9 => (14 - y) + 2y = 9
14 + y = 9 => y = -5
x + (-5) = 14 => x=19
