7x+2y=-17
steps:
x=2x + 5x
y=3y - y
sum=-5 -12
Answer:
Always
Step-by-step explanation:
A mononomial's variable can only have exponents 0,1,2,3 etc so the product will also be a mononomial.
The amount of money that Layla has saved, s, is going to be what the equation equals. She earns $150 each month, so that would be 150m (slope intercept form equation s=em+b). B is the y-intercept, or the amount that Layla already has saved, which is positive $650.
Your equation is:
s=150m+650
I hope this helps :)
Equation to find number's value: 
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as
.
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation: 
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation
, which is the same thing as the equation we were using.
Now add n and
together to get
.
After you do this, your equation should look like
.
Now divide both sides by
to get n's value.
n = 35
