3 to the power of 2- 2x3 + 5

−2x^3+13

Step-by-step explanation:

Let's simplify step-by-step.

23−2x^3+5

=8+−2x^3+5

Combine Like Terms:

=8+−2x^3+5

=(−2x^3)+(8+5)

=−2x^3+13

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
