Question

7x-4+9x-3x= 12-5x+3x-2+x

Answer 1

7x−4+9x−3x=12−5x+3x−2+x

Combine 7x and 9x to get 16x.

16x−4−3x=12−5x+3x−2+x

Combine 16x and −3x to get 13x.

13x−4=12−5x+3x−2+x

Combine −5x and 3x to get −2x.

13x−4=12−2x−2+x

Subtract 2 from 12 to get 10.

13x−4=10−2x+x

Combine −2x and x to get −x.

13x−4=10−x

Add x to both sides.

13x−4+x=10

Combine 13x and x to get 14x.

14x−4=10

Add 4 to both sides.

14x=10+4

Add 10 and 4 to get 14.

14x=14

Divide both sides by 14.

x=

14

14

​

Divide 14 by 14 to get 1.

x=1
