Answer:
x= -12
Step-by-step explanation:
move variable to left and change its sign
= 4x - 20 = -68
move constant to the right and change its sign
= 4x = -68 + 20
calucate the sum
= 4x = -48
divide both sides of the equation by 4
x= -12
Answer:
A. 5
Step-by-step explanation:
12 times 5 is 60 plus 10 is 70. 70 < 75
Answer:
A)
– 6x – 2x = 16
-8x = 16
x = 16/-8 = -2
B)
3(3x – 6) = 18
9x - 18 = 18
9x = 18 + 18 = 36
x = 36/9 = 4
C) ASSUMING YOU MADE AN ERROR BY WRITING 0 INSTEAD OF (
5(2x + 3) =-4(-5 – 2x)
10x + 15 = 20 + 8x
10x - 8x = 20 - 15
2x = 5
x = 5/2
12x =
