Answer:

p = -8

Step-by-step explanation:

9+-2p=25

Subtract 9 from each side

9+-2p-9=25-9

-2p = 16

Divide each side by -2

-2p/-2 = 16/-2

p = -8

Answer:

-8

Step-by-step explanation:

To solve for the equation, you are looking to solve for the p's value. Our goal is to isolate p by itself.

9+-2p=25

Subtract 9 from both sides.

-2p=25-9

-2p=16

Divide both sides by -2 (to isolate p by itself).

-2p/-2 = 16/-2

p = -8

Solve for c. -c/2+43 = 50

$\huge\text{Hey there!}$

$\mathsf{-\dfrac{c}{2}+43=50}$

$\large\text{SUBTRACT 43 to BOTH SIDES}$

$\mathsf{-\dfrac{c}{2}+43-43=50-43}$

$\large\textsf{CANCEL out: 43 - 43 because that gives you 0}$

$\large\textsf{KEEP: 50 - 43 because it helps solve for the c-value}$

$\mathsf{50 - 43 = \bf 7}$

$\large\text{NEW EQUATION: }\mathsf{-\dfrac{c}{2}=7}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{2}{-1}}\large\textsf{ to BOTH SIDES}$

$\mathsf{\dfrac{2}{-1}\times-\dfrac{c}{2}= \dfrac{2}{-1}\times7}$
