Answer 1

Answer:

5(x+4) =30

-multiply 5 and x then multiply 5 and 4

- That gives you 5x+20=30

-subtract 20 from 30 and positive 20 that gives you 5x=30

-divide 5x by 5 that cancels each other out

-divide 30 by 5 that gives you x=6

-4(3x+2)=32

-multiply -4 by 3x that gives you -12x

-then multiply -4 by positive 2 that gives you -8

-now you have -12x-8=32

-add both sides by 8

- -12x=40

- divide 12x by 12 that cancels each other out

- divide 40 by 12

- that gives you 3.3 (repeating)

1/2(9x+15) =20

-multiply 1/2 by 9x that gives you 4.5x

-multiply 1/2 times 15 that gives you 7.5

- 4.5x+7.5=20

- subtract both sides by 7.5

-4.5x=20

- divide both sides by 4.5

- 4.5x divided by 4.5 cancels out

- 20 divided by 4.5 gives you 4.4 (repeating)

-4(1.5-x) =9

-multiply -4 by 1.5 that gives you -2.6

- multiply -4 by -x that gives you 4

- -2.6+4=9

- subtract both sides by 4

- 2.6x= 5

- divide 2.6x by 2.6 that cancels each other out

- divide 5 by 2.6 that gives you 1.9

(sorry I took so long Hope this helps!)

Answer 2

Answer:

x=3.75

Step-by-step explanation:

-4(1.5-x)=9

first distribute

6-4x=9

then isolate the variable
