Question

the quantity of x plus 20 over 2 = 3x

Answer 1

x + 20/2 = 3x
multiple both sides by 2 to get rid of the 2
2(x+20/2) = 3x(2)
the 2s cancel each other out on the left side
x+20=6x
you want to get the x's on the same side
so subtract x from each side
20=5x
divide both sides by 5 to get x on its own
20/5 = 5x/5
4=x

Answer 2

x + 20/2 = 3x
or 2x=10
x=5

Answer 3

ty whats the answr to this? 1 over 3 (2x − 8) = 4

Answer 4

@doubledrive what aout this 1 over 3 (2x − 8) = 4

Answer 5

Multiply both sides of the equation by 3 to cancel the fraction

3((1/3)(2x-8)) = 4(3)

1(2x-8) = 12

2x - 8 = 12

2x = 12 + 8

2x = 20

x = 20/2

x = 10

Answer 7

You sure you aren't asking?:
\[\frac{(x+20)}{2}= 3x\]
