Question

Solve. 3(2x - 1) = 45

Answer 1

Given,

The expression is

`3\mleft(2x-1\mright)=45`

Simplifying the expression using the BODMAS rule, first open the small bracket.

`6x-3=45`

Adding 3 to both sides then,

`\begin{gathered} 6x-3+3=45+3 \\ 6x=48 \end{gathered}`

Dividing both sides by 6 then,

`\begin{gathered} (6x)/(6)=(48)/(6) \\ x=8 \end{gathered}`

Hence, the value of x is 8.
