When figuring out the amount of mulch would be needed for alex's back yard, he created an equation that

approximates the number of bags, b, he'll use. if his equation is b = 4(2x +7)+3(2x +7) and (2x+7) is

equal to 2, how many bags will he need? show your mindful manipulations.

Alex will need 14 bags

Step-by-step explanation:

B= 4(2x+7)+3(2x+7)

and

2x+7=2

First, we should solve the second equation to obtain x:

2x+7=2

2x=2-7

x= -5/2

Then, we use this answer to calculate B:

B=4(2(-5/2)+7)+3(2)

B=4(-5+7)+6

B=4(2)+6

B=8+6

B=14

Alex will need 14 bags

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
