Let’s say the unknown number is x.
therefore,
(2x)^2/3 - 30= 18
4x^2/3 -30 = 18
4x^2-90/ 3 = 18
multiply 18 by 3, and 4x^2-90 by 1
hence,
4x^2-90 = 54
4x^2=144
x^2= 144/4
x^2= 36
x=+ or - 6
hope it helps:)

Solve for x:<br><br> 2(3x - 9) = 18x<br><br> x = -3/2<br><br> x = 3/2<br><br> x = 0<br><br> x = 6
Mila [183]
Remember yo can do anything to an equation as long as you do it to both sides

so
remember distributive property
a(b+c)=ab+ac

so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x

easier way is to first divide both sides by 2


x=-3/2
