​

Answer 1

Answer:

11.25

Step-by-step explanation:

4x-30=33-18

4x=15+30

4x=45

x=45/4

x=11.25

Answer 2

Let's solve your equation step-by-step

$15+3(4x-30)=33$

Step 1: Simplify both sides of the equation.

$15+3(4x-30)=33$

(Distribute)

$15+(3)(4x)+(3)(-30)=33$

$15+12x+-90=33$

(Combine Like Terms)

$(12x)+(15+-90)=33$

$12x+-75=33$

Step 2: Add 75 to both sides.

$12x-75+75=33+75$

$12x=108$

Step 3: Divide both sides by 12.

$\frac{12x}{12} =\frac{108}{12}$

$x=9$

∴ $x=9$ in the following equation.
