Question

1. Solve the equation. Answer with an integer or fraction.
`(4)/(7) x`+ 9 = 5

Answer 1

Question

`(4)/(7)\text{ x + 9 = 5}`

First collect like terms.

`\begin{gathered} (4)/(7)\text{ x = 5 - 9} \\ (4x)/(7)\text{ = -4} \\ \text{Cross multiply} \\ 4x\text{ = -4 x 7} \\ 4x\text{ = -28} \\ x\text{ = }(-28)/(4) \\ x\text{ = -7} \end{gathered}`
