Question

how to do this equation

-3+10y+6= 15+12y-18

 

Answer 1

  -3 + 10y + 6 = 15 + 12y - 18
   ↑     3       ↑     ↑     -3      ↑  combine like terms

10y + 3 = 12y - 3
10y - 12y + 3 - 3   = 12y - 12y - 3 - 3
-2y = -6
(-2y) / 2 = (- 6) / 2
y = 3

Answer 2

10y-12y = 15+3-6-18 -2y = -6 y = 6/2 = 3

Answer 3

To find y

First, rearrange the order: 10y-3+6=12y+15-18

Second, add the constant: 10y+3=12y-3

Third, subtract 3 to both side: 10y+3-3=12y-3-3

10y=12y-6

Forth, subtract 12y to both side: 10y-12y= 12y-12y-6

  -2y=-6

Last, divide -2 to both side: -2y/-2=-6/-2

y=3
