Answer:
its 56
Step-by-step explanation
50% × x = 28 or, 50 100
× x = 28
Multiplying both sides by 100 and dividing both sides by 50,
we have x = 28 ×
100
50
x = 56
If you are using a calculator, simply enter 28×100÷50, which will give you the answer.
2x + 12y = -1
12y = -1 - 2x
y = -1/6x - 1/12
How to solve them? Just move over the variables to one side and solve for them until you have just the variable, whilst doing the same actions to the side with only numbers. For parentheses with a coefficient, use distributive method.
