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,

$\begin{gathered} \frac{6x}{6}=\frac{48}{6} \\ x=8 \end{gathered}$

Hence, the value of x is 8.
