Sorry...I dont understand......
1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
Answer:
whats the other function besides p
Step-by-step explanation:
Divide both sides by 2
subtract 10 from both sides
2(x + 10) = 60
x + 10 = 60/2
x + 10 = 30
x = 30 - 10
x =20
subtract 20 from both sides
divide both sides by 2
2x + 20 = 60
2x = 60 - 20
2x = 40
x = 40/2
x = 20

Answer:
36 minutes
Step-by-step explanation:
The key is to get the same amount of time for each.
9 * 12 = 108
At 12 minutes per job,
in 108 minutes Alyssa could do
108/12 = 9 jobs
At 9 minutes per job,
Together in 108 minutes they could do
108/9 = 12 jobs
--------------------------
In 108 minutes Mirada does
12 - 9 = 3 jobs
108/3 = 36 minutes per job
