Question

Find X: 50+5x=30 (will mark)

Answer 1

Answer:
`-4`

Simplify both sides of the equation

`5x+50=30`

Subtract 50 from both sides

`5x+50-50=30-50\\5x=-20`

Divide both sides by 5

`5x/5=-20/5\\x=-4`

Answer 2

`50 + 5x = 30 \\ 5x = 30 - 50 \\ 5x = - 20 \\ (5x)/(5) = ( - 20)/(5) \\ x = ( - 4)`
