-x + y = -13 → -3x + 3y = -39
-4x + 3y = -51 → -4x + 3y = -51
x = 12
-x + y = -13
-(12) + y = -13
-12 + y = -13
+ 12 + 12
y = -1
(x, y) = (12, -1)
Answer:
x+z=m
Step-by-step explanation:
First, we can do distributive property.
-3(n + 8) = 15
-3 x n = -3n, -3 x 8 = -24
So we have, -3n + -24 = 15
Minus -24 on both sides of the equal sign.
-3n + -24 - -24 = 15 - -24
-3n = 39
Divide 3 on both sides.
-3n/-3 = 39/-3
n = -13
Hope i helped!! :D
