Answer: x=-1
Step-by-step explanation:
8-3x-x=12
-3x-x=-4x
8-4x=12
-8 -8
-4x=4
-4x/-4=4/-4
x=-1
V = 1/3 l h w
V = 1/3 (12)(15)(9)
V= = 540
answer 540 m^3
Answer:
one solution
Step-by-step explanation:
Given
3x - 2 = 4x + 5 ( subtract 4x from both sides )
- x - 2 = 5 ( add 2 to both sides )
- x = 7 ( multiply both sides by - 1 )
x = - 7 ← the one solution
