4x^2-24x+4y^2+72y=76
podryga [215]
<span>Simplifying 4x2 + -24x + 4y2 + 72y = 76
Reorder the terms: -24x + 4x2 + 72y + 4y2 = 76
Solving -24x + 4x2 + 72y + 4y2 = 76
Solving for variable 'x'.
Reorder the terms: -76 + -24x + 4x2 + 72y + 4y2 = 76 + -76
Combine like terms: 76 + -76 = 0 -76 + -24x + 4x2 + 72y + 4y2 = 0
 Factor out the Greatest Common Factor (GCF), '4'. 4(-19 + -6x + x2 + 18y + y2) = 0
 Ignore the factor 4.

</span><span>Subproblem 1
Set the factor '(-19 + -6x + x2 + 18y + y2)' equal to zero and attempt to solve: Simplifying -19 + -6x + x2 + 18y + y2 = 0 Solving -19 + -6x + x2 + 18y + y2 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Crank
The answer is indeed 3,725.90. The reason why is because <span>with each adjustment, you take the remaining balance and calculate a fixed rate loan for the remaining time period at the new rate. When you follow that procedure with the data you already have, you get that answer.</span>

What is the solution to the equation?
Lisa [10]
3q + 5 = -2q + 20

add 2q to both sides.

5q + 5 = 20

subtract 5 to both sides.

5q = 15

divide 5 to both sides.

q = \frac{15}{5}

the answer is: q = 3
