Answer:
5
Step-by-step explanation:
-x = 4 - 3x + 6
3x-x = 4 + 6
2x = 10
x = 5
Answer:
6x=54
Step-by-step explanation:
3x - {7-x} =29
open bracket
3x - 7 +x =29
collect like terms and equate
4x =29 +7
4x = 36
divide both sides by 4
x = 9
.
. . 6x= 6 × 9 = 54
6x= 54
I am gonna have to go with Latisha's answer.
(x - 3)(x + 4) = x^2 + 4x - 3x - 12 = x^2 + x - 12.......and 4(-3) = -12, -3 + 4 = 1....and the factors are correct
