Solve the Equations

Vikentia [17]

Answer:

1) -2.13

2) 2.57

3) 33

Step-by-step explanation:

3(8 + 5h) = -28 Distribute the 3

24 + 15h = -28 Subtract 24 from both sides of the equation

15h = -32 Divide both sides by 15 and round

h = - 2.13

19 = 7(3n - 5) Distribute the 7

19 = 21n - 35 Add 35 to both sides of the equation

54 = 21n Divide both sides of the equation by 21

2.57 = n

6s - 7s = -33 Combine the s's

-s = -33 Multiply both sides by -1

s = 33
