Answer:

x = 25

Step-by-step explanation:

2x-20=30

First, isolate the term with x in it by moving everything else to the other side:

2x = 30 + 20

Simplify like terms:

2x = 50

Further isolate the x by dividing by 2 on both sides:

2x/2 = 50/2

The 2 cancels out on the left, leaving:

x = 25

Answer:

x= 25

Step-by-step explanation:

Simplifying 2x + -20 = 30

Reorder the terms: -20 + 2x = 30

Solving -20 + 2x = 30

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '20' to each side of the equation. -20 + 20 + 2x = 30 + 20

Combine like terms: -20 + 20 = 0 0 + 2x = 30 + 20 2x = 30 + 20

Combine like terms: 30 + 20 = 50 2x = 50

Divide each side by '2'. x = 25

Simplifying x = 25
