Question

4(2x - 5) + 15 = 11?

Answer 1

The equation is given below as

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

Expand the brackets above, we will have

`\begin{gathered} 4(2x-5)+15=11 \\ 8x-20+15=11 \\ 8x-5=11 \end{gathered}`

Collect similar terms, we will have,add 5 to both sides

`\begin{gathered} 8x-5=11 \\ 8x-5+5=11+5 \\ 8x=16 \\ (8x)/(8)=(16)/(8) \\ x=2 \end{gathered}`

Hence,

The value of x= 2

Answer 2

x= 2.

Explanation:

1. Write the expression.

`4(2x - 5) + 15 = 11`

2. Multiply to solve the parenthesis.

`(4)(2x)+(4)(-5) + 15 = 11\\ \\8x+(-20) + 15 = 11\\\\8x-20 + 15 = 11\\ \\8x-5 = 11`

3. Add 5 to both sides of the equation.

`8x-5+5= 11+5\\ \\8x= 16\\ \\`

4. Divide both sides by 8.

`(8x)/(8) = (16)/(8) \\\\x= 2`

5. Express your result.

x= 2.
