Answer:
The number is 8.
Step-by-step explanation:
Let that "certain" number be x.
3x+4=28
3x=28-4
3x=24
x=24/3
x=8
Answer:
x = (18 + 3y)/2 y = (18 - 2x)/3
Step-by-step explanation:
For whichever variable you want to solve for, isolate it on one side. For example, if you want to solve for x, first add 3y to each side.
2x = 18 + 3y
Then, divide everything by two.
x = (18 + 3y)/2
