How to solve -7+2x = -6x -71

x = -8

Step-by-step explanation:

to solve this kind of problem is very simple , just be very careful about the negative and positive signs.

-7+2x = -6x -71

we will collect the like terms or simply say that you will combine the like terms

we  have,

-7 + 2x + 6x = -71

2x + 6x = -71 + 7

8x = -64

divide both sides by 8

8x/8 = -64/8

x = -8

the area of the mat = total area added minus the original area of the water color painting.

length of the mat is:

L = 21 in + 3 in + 3 in because 3 in  is added to each side

L = 27 inwidth of the mat is:w = 11 in + 3 in + 3 inw = 17in

Area mat = (27 in x 17 in) - ( 21 in x 27 in)

area mat = 108 sq in is the area of the mat
