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
