Can someone help me with the answers

m = 32. k = 23/53. p = -8

Step-by-step explanation:

21 = 4m + 7 + 2

add the numbers

21 = 4m + 9

move variable ot the left hand side and change its sign

-4m + 21 = 9

calculate the difference

-4m = -12

divide both sides

m = 3

17= 5k + 1 - 7

calculate the difference

17 = 5k - 6

move variable to the left hand side and change its sign

-5k + 17 = -6

calcuate the difference

-5k = -23

divide both sides

k = 23/5

2(-8p+8) = 144

divide both sides of the equation by 2

-8p + 8 = 72

Move the constant to the right hand side and change its sign

-8p = 72 - 8

subtract the numbers

-8p = 64

divide both sides of the equation by -8

p = -8
