solve 6z=(-84)

-14

14= -s/5

-70=s

solve 4=n-(-3)

1

a number is divide by four. the result is added to five. this result is multiplied by three to give 27. what is the number.

16

solve x-12=5

17

translate the following sentence into a verbal equation. a number n added to 18 is seven times the different of n and three

18=n = 7 (n times 3)

1/9=y- 5/9

2/3 =y

solve -15 = (-w/3)

45

solve -4/5s =(-28)

49

10/27= a/135

51=a

translate the following sentence into an equation. the product of five and a number y is less then the quotient of four and y.

5y = 4/y - 2

solve 2+7y =44

6

-5=v-12

7=v

7+t =11

T=4

3 - 5b = -32

b=7

translate the following equation into a verbal sentence. 3/y -5 = x(y+7)

three divided by y minus five is a number x times the sum of y and seven.

translate the following equation into a verbal sentence. x(7 - 5y) = x/2

x times the difference of seven minus the product of five y equals the quotient of x and two.

-8x=-56

x=7

-7/9y = -6

y= 54/7
