1.
Find the length L of a rectangle with a width W=6 and a perimeter of P=36
P=2L%2B2W....plug in given values
36=2L%2B2%2A6
36=2L%2B12
36-12=2L
24=2L
highlight%2812=L%29

2.
5 more than a number is 2. what is the number?
let number be x
5 more than a number is x%2B5
than 5 more than a number is 2 is: x%2B5=2...now, solve for x
x%2B5-5=2-5
highlight%28x=-3%29

3.
x%2F7+-+10+=4
x%2F7+=4%2B10
x%2F7+=14
x=14%2A7
highlight%28x=98%29


4.
Solve for+x: 5x+%2B+2y+=9

5x+=9-2y
x+=9%2F5-2y%2F5..rearrange terms on right side
x+=-2y%2F5%2B9%2F5
highlight%28x+=-%282%2F5%29y%2B9%2F5%29
