Question

Equation with variables on both sides: decimals & fractions 4x + 8 = 7.2 + 5x

Answer 1

Final Answer:
`x = 0.8`

Steps/Reasons/Explanation:

Question: Equation with variables on both sides: decimals & fractions
`4x + 8 = 7.2 + 5x`.

Step 1: Subtract
`4x` from both sides.

`8 = 7.2 + 5x - 4x`

Step 2: Simplify
`7.2 + 5x - 4x` to
`7.2 + x`.

`8 = 7.2 + x`

Step 3: Subtract
`7.2` from both sides.

`8 - 7.2 = x`

Step 4: Simplify
`8 - 7.2` to
`0.8`.

`0.8 = x`

Step 5: Switch sides.

`x = 0.8`

Answer 2

4x + 8 = 7.2 + 5x

1. 4x - 4x + 8 = 7.2 + 5x - 4x

2. 8 = 7.2 + x

3. 8 - 7.2 = 7.2 - 7.2 + x

4. 0.8 = x
