Answer:
A
Step-by-step explanation:
Steps:
(x-2)=4x
Pretend that there is a one in front of x-2
1(x-2)=4x
Multiply the bracket by 1
x-2=4x
Move x to the other side .Whenever you move a number or letter the sign changes.
x-x-2=4x-x
-2=3x
Divide by 3 for -2 and 3
-2/3=3/3 x
x=-2/3
Check answer by using substitution method
(-2/3-2)=4(-2/3)
(-2/3-6/3)=-8/3
-8/3=-8/3
Answer is -2/3
7(z +2) - 3z =44
Distribute the 7. Distributive property: a(b+c) = ab + ac
7z + 14 - 3z = 44
Simplify like terms.
4z + 14 = 44
Subtract 14 to both sides
4z = 30
Divide by 4 on both sides.
z = 7.5

Answer:
X=-50
Step-by-step explanation:
18=-1/2x-7
-1/2x=18+7...... this is first step
X=25/(-1/2)...... the 2nd step
X=-50
