Hey friend here's your answer
Answer:
x=16
Step-by-step explanation:
2x+1=31
2x=32
x=16
Simplifying
2x + -1 = 31
Reorder the terms:
-1 + 2x = 31
Solving
-1 + 2x = 31
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 2x = 31 + 1
Combine like terms: -1 + 1 = 0
0 + 2x = 31 + 1
2x = 31 + 1
Combine like terms: 31 + 1 = 32
2x = 32
Divide each side by '2'.
x = 16
Simplifying
x = 16
