Question

Solve for x, 3x+21=8x*54

Answer 1

`x=(7)/(143)`

Explanation:

Simplify the right side of the equation.
`3x+21=432x`. Subtract 21 from both sides of the equation.
`3x=432x-21`. Subtract 432x from both sides of the equation,
`-429x=-21`. The negative signs cancel out to get
`429x=21`. Divide both sides but 429 to get
`x=(21)/(429)`. Reduce to get
`x=(7)/(143)`.

Answer 2

Exact form: 7/143

Decimal form: /0.048951
