solve for the indicated variable. include all of your work in your answer. submit your solution. p = 2l + 2w ; for l

Since l is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.2l+2w=PMove all terms not containing l to the right-hand side of the equation.More StepsSince 2w does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2w from both sides. 

2l=−2w+P 
2l=−2w+PDivide each term in 2l=−2w+P by 2 to eliminate the fractions.More StepsDivide each term in 2l=−2w+P by 2.

Cancel the common factor. 

 2 l 2 =−2w2+P2 

Divide l by 1 to get l. 

l=−2w2+P2 

Cancel the common factor. 

l=− 2 w 2 +P2 

Divide w by 1 to get w. 

l=−w+P2 
l=−w+P2 

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
