Question

Hi I don't really understand could u help me4(2x - 5) + 15 = 11I have to Write the steps

Answer 1

Solution

- The question would like us to find the value of x in the expression below:

$4\left(2x-5\right)+15=11$

- The solution steps are given below:

$\begin{gathered} 4\left(2x-5\right)+15=11 \\ \text{ Subtract 15 from both sides} \\ \\ 4(2x-5)+15-15=11-15 \\ 4(2x-5)=-4 \\ \text{ Expand the bracket} \\ \\ 4(2x)-4(5)=-4 \\ 8x-20=-4 \\ Add\text{ 20 to both sides} \\ \\ 8x-20+20=-4+20 \\ 8x=16 \\ Divide\text{ both sides by 8} \\ \\ \frac{8x}{8}=\frac{16}{8} \\ \\ \therefore x=2 \end{gathered}$

Final Answer

The answer is

$x=2$
