Answer:
[tex]\frac{1}{2}x+4=30[/tex]
52
Step-by-step explanation:
First, write the equation out in the algebraic form. Half of a number is equivalent to a number times 1/2. Additionally, increasing a number by 4 is just adding 4. So the equation is [tex]\frac{1}{2}x+4=30[/tex].
Then, use algebra to solve.
1) Subtract 4 from both sides
1/2x=26
2) Multiply both sides by 2, because that is the same as dividing by a fraction
x=52
