Question

I need help figuring out 121+2=9(-6-7P)+4P

Answer 1

Hi,


Work:


Equation;

$121 + 2 = 9( - 6 - 7p) + 4p$

First add up numbers and distribute 9 over parenthesis.

$123 = - 54 - 63p + 4p$

Second: collect like terms.

$123 = - 54 - 59p$

Move variable 59p to left side and change its sign.

$59p + 123 = - 54$

Then move constant 123 to right side and change its sign.

$59p = - 54 - 123$

Calculate the difference.

$59p = - 177$

Divide both sides of equation by 59.

$p = - 3$


Hope this helps.
