Hey, just follow these steps:
Simplifying:
10 = (2x + 1)
Reorder the terms:
10 = (1 + 2x)
Remove parenthesis around: (1 + 2x)
10 = 1 + 2x
Solving
10 = 1 + 2x
Solving:
10 = 1 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
10 + -2x = 1 + 2x + -2x
Combine like terms: 2x + -2x = 0
10 + -2x = 1 + 0
10 + -2x = 1
Add '-10' to each side of the equation:
10 + -10 + -2x = 1 + -10
Combine like terms: 10 + -10 = 0
0 + -2x = 1 + -10
-2x = 1 + -10
Combine like terms: 1 + -10 = -9
-2x = -9
Divide each side by '-2'.
x = 4.5
Simplifying
x = 4.5
x = 4.5
Hope I helped : )
