1/2x + 3 = 18
[tex]x = 30[/tex]
1st step: Combine multiplied terms into a single fraction.
[tex] \frac{1}{2} x \: + 3 = 18[/tex]
[tex] \frac{1x}{2} + 3 = 18[/tex]
2nd step: Multiply by 1
[tex] \frac{1x}{2} + 3 = 18[/tex]
[tex] \frac{x}{2} + 3 = 18[/tex]
3rd step: Subtract 3 from both sides of the equation
[tex] \frac{x}{2} + 3 = 18[/tex]
[tex] \frac{x}{2} + 3 - 3 = 18 - 3[/tex]
4th step: Simplify
Subtract the numbers -> Subtract the numbers
[tex] \frac{x}{2} = 15[/tex]
5th step: Multiply all terms by the same value to eliminate fraction denominators
[tex] \frac{x}{2} = 15[/tex]
[tex]2 \times \frac{x}{2} = 2 \times 15[/tex]
6th step: Cancel multiplied terms that are in the denominator
[tex]2 \times \frac{x}{2} = 2 \times 15[/tex]
[tex]x = 2 \times 15[/tex]
7th step: Multiply the numbers
[tex]x = 2 \times 15[/tex]
[tex]x = 30[/tex]
