Answer:
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 .
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
Answer:
0
Step-by-step explanation:
This system has 0 solutions because the two equations directly contradict each other so there can't be a value that fits both.
