Answer:
Step-by-step explanation:
Let's start with an equation like 2x+4=10. We have to isolate x to get an answer. We go for the number without the variable first.
2x+4=10
Subtract 4 from both sides.
2x+4-4=10-4
2x=6
Divide by 2.
2/2=6/2
x=3
There you go!
Answer:
a = -2(2x+1)-4
Step-by-step explanation:
1. Factor out the common term x.
x(4+a)= -2x(2x+1)
2. Cancel x on both sides.
4+a= -2(2x+1)
3. Subtract 4 from both sides.
a= -2(2x+1)-4
