Answer:

a can be anything. There are infinite solutions.

Step-by-step explanation:

4(a+2)=8+4a

Expand:

4a+4\times\:2=8+4a

4a+8=8+4a

Subtract 8 from both sides:

4a+8-8=8+4a-8

4a=4a

Subtract 4a from both sides:

4a-4a=4a-4a

0=0

Since both sides are equal, a has infinite solutions as no matter what value it is, it will not affect the end result of 0=0 which is true.

lord [1]

Answer:

x=5

Step-by-step explanation:

x+5 = -3x+25

Add 3x to each side

x+3x+5 = -3x+3x+25

4x +5 = 25

Subtract 5 from each side

4x+5-5 = 25-5

4x = 20

Divide each side by 4

4x/4 = 20/4

x =5
