Brenden. the more plants you test the easier it is to find the average instead of a smaller amount. hope this helped!
10h+120p=950.50
h+p=12
p=?
h+p=12
-p both sides
h=12-p
plug in to 10h+120p=950.50
10 (12-p)+120p=950.50
distribute
120-10p+120p=950.50
simplify
120+110p=950.50
-120 both sides
110p=830.50
÷110 both sides
p=7.55
Step-by-step explanation:
first you have to take all similar variable on the same side of the equation and the constants on the other side then solve the question .
example : -12x + 9 = -15x
-12x +15x = -9
3 x = -3
X = -3/3= -1
x = -1
like this you can solve all the other equation ..
