Question

4. Solve this equation. Explain or show your reasoning. 5x+7= 12)

Answer 1

`5x+7=12`

to solve this equation we do operations on both sides to find x

for example if we subtract 7 on both sides

`\begin{gathered} 5x+7-7=12-7 \\ 5x=5 \end{gathered}`

now we divide between 5 on both sides

`\begin{gathered} (5x)/(5)=(5)/(5) \\ \\ x=1 \end{gathered}`

the value of x is 1
