Answer:
P = - 15
Step-by-step explanation:
P+7-5 = -10 - 3
P +2 = - 13
(If taking from one side,you must do to the other to get P alone.)
P+2 = - 13
-2 = - 2
The positive 2, minus the negative 2 cancels each other out, now we must subtract 2 from our other side. - 13 - 2 = - 15
P = -15
32 degees, 43.8 degrees, 53.8, 63.8 Yes they are proportional
For this case we must solve the following linear equation:

Adding similar terms from the left side of the equation:

Subtracting
from both sides of the equation we have:

Thus, equality is not fulfilled. So the equation has no solution.
Answer:
No solution
An equation is formed of two equal expressions. The solution is (-9,-2).
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the equation x + 3y = -15 and -3x + 2y = 23,
Step 1- Multiply the equations to make the coefficients match in either the x- or y-variable.
x + 3y = -15
3x + 9y = -45
Step2- After you multiply, add or subtract the two equations.
3x + 9y -3x + 2y = -45 + 23
Step 3- Then solve for the variables that is left.
11y = -22
y = -2
Step4- Substitute the value of y in any one of equations to solve for x.
x + 3(-2) = -15
x - 6 = -15
x = -9
Hence, The solution is (-9,-2).
