Question

Solve and check the following equations. Show your solution.

12.) 18 = 2x - 14
13.) 4y - 8y = 4 - 32
14.) 4y - 19 = -6y + 11 ​

Answer 1

12. 16

13. 7

14. 3

Explanation:

12. 18= 2X-14

Collect like terms

18+14=2X

32=2X

divide both side by 2

X= 32/2=16

13. 4y-8y=4-32

-4y = -28

Divide both side by -4

y= -28/-4

y= 7

14. 4y-19= -6y+11

Collect like terms

4y+6y= 11+19

10y= 30

Divide both side by 10

y= 30/10

y= 3
