Question

Problem: 7x - 3 (2x - 9) = 6x + 3
Please give me a clear explanation, I'm new to this unit.

Answer 1

Answer:
`x=(24)/(5)` , (decimal: x=4.8)

Explanation:

`7x-3\left(2x-9\right)=6x+3`

`7x-6x+27=6x+3`

`x+27=6x+3`

`x+27-27=6x+3-27`

`x=6x-24`
`x-6x=6x-24-6x`

`-5x=-24`

`(-5x)/(-5)=(-24)/(-5)`

`x=(24)/(5)`

Answer 2

`x=(24)/(5)`

Explanation:

`7x-3\left(2x-9\right)=6x+3`

Use the distributive property to multiply -3 by 2x-9:-

`7x-6x+27=6x+3`

Combine 7x and -6x to get x:-

`x+27=6x+3`

Subtract 6x from both sides:-

`x+27-6x=3`

Combine x and -6x to get -5x:-

`-5x+27=3`

Subtract 27 from both sides:-

`-5x=3-27`

`-5x=-24`

Divide both sides by -5:-

`x=(24)/(5)`
