Y - x = 9
12 = 1/3x
The first thing you want to do when solving a system of equations is isolating one of the variables.
Since the second equation only contains x, we can isolate x in the first equation.
y - x = 9
y = x + 9
x = y - 9
You can also solve the second equation without any previous solving.
12 = 1/3x
Multiple both sides by 3/1 or 3
x = 36
Now we can set them equal to each other
36 = y - 9
y = 45
Answer: x = 36 and y = 45
Answer:
108
Step-by-step explanation:
let x be hourly rate
1508. --. 14hours
x --. 1 hour
cross multiply
14x= 1508
x=1508÷14
x= 108(approximately)
