combine like terms 't left side first you need to find y \[\huge\rm \color{reD}{12y}\color{blue}{-10}\color{blue}{+51}+\color{reD}{30y}+\color{blue}{13 }=180\]

you can think of the 12y -10 as 12y + (-10) you can re-arrange the additions to look like this 12y + 30y + (-10) +51+13 = 180 add up: 12 y's plus 30 more y's is how many y's? and the numbers: 51+13 + -10= ? you should get 42y +54= 180 now add -54 to both sides (write -54 on both sides) and then simplify
