Question

The question is 4x-5=16 and we have to round the solution to two decimal places

Answer 1

Given: 4x - 5 = 16

Solve for x

`\begin{gathered} 4x-5=16 \\ \text{Add }+5\text{ to both sides} \\ 4x-5+5=16+5 \\ \text{The }-5+5\text{ is cancelled out which leaves }4x\text{ on the left side},\text{ simplify the right side} \\ 4x=21 \\ \\ \text{Then divide both sides by 4} \\ 4x=21 \\ (4x)/(4)=(21)/(4) \\ x=5.25 \end{gathered}`

Therefore, the solution is x = 5.25.
