7•?=x

x+20=p

p+x=180

80/7 or 11.429

Step-by-Step explanation:

so first we define x in terms of p (or p in terms of x)

x=180-p

replace x in the equation x+20=p with 180-p

180-p+20=p

add p to each side

200=2p

p=100

so now we can find x

180-p=x

180-100=x

x=80

say z=?

7=80/z

multiply both sides by z

7z=80

divide both sides by 7

z=80/7

?=11 3/7

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
