The difference (-) between 15 and the product (x) of 15 and y
15y - 15
System: x + y = 44; x = 2y + 2
Solve with substitution: x = 30; y = 14
x + y = 44
x = 2y + 2
Substitute 2y + 2 for x
2y + 2 + y = 44
3y + 2 = 44
Subtract 2 on both sides.
3y = 42
y = 14
Now substitute back in.
x + 14 = 44
Subtract 14 on both sides.
x = 30
First, you would need to create an equation for this problem.

=

Next, you would cross multiply.
5x = 8,000
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 5.

Step-by-step explanation:
Using the half-angle formula ...

We can let θ = π/4 and simplify the result as follows:

125 per month-$20 per month expences=105 savings each month
800/105= number of months needed to save
Answer 7.6 (rounded) roughly about 7 and a half months. If shes paid monthly, then 8 montjs needed
