One Step Equationssss!?

Question

42. Solve One Step Equations

a) z – 7 = -3

b) p + -7 = 9

c) 8 + p = -4

d)17=x/3

e) 30x = 480

f) 2/3x =30

Answer 1

a) z = 7 -3 = 4

b) p = 9 + 7 = 16

c) p = -4 - 8 = -12

d) x = 17 * 3 = 51

e) x = 480/30 = 16

f) 2/3x = 30 =>

   x = 30 (3/2) =>

   x = 45

Answer 2

f) is the toughest

2/3 * x = 30; by multiply both side by 3/2 we have

x = 45

Answer 3

a) add 7

b) add 7

c) subtract 8

d) multiply by 3

e) divide by 30

f) divide by 3/2

Answer 4

a)4

b)16

c)-12

d)51

e)16

f)45
