Question

Solve each equation. Check your answer. 2(x+4)=8

Answer 1

x = 0

Explanation:

Solve each equation. Check your answer. 2(x+4)=8

2(x + 4) = 8

2x + 8 = 8

2x = 0

x = 0

------------------------

check

2(0 + 4) = 8

0 + 8 = 8

8 = 8

same value the answer is good

Answer 2

The answer is:

x = 0

Work/explanation:

To solve, distribute 2:

`\bf{2(x+4)=8}`

`\bf{2x+8=8}`

Subtract 8 on each side

`\bf{2x=8-8}`

`\bf{2x=0}`

Divide each side by 2

`\bf{x=0}`

Hence, x = 0.

`\rule{350}{4}`

Now, to check our answer, we plug in the solution that we just obtained into the original equation, i.e., 2(x + 4) = 8

We got that x = 0, so we plug that in:

`\bf{2(0+4)=8}`

Add:

`\bf{2(4)=8}`

Multiply

`\bf{8=8}`

Since the left side equals the right side, the answer, x = 0, is indeed the correct one.
