Accepted Solution
A:
52+4y=12We move all terms to the left:52+4y-(12)=0We add all the numbers together, and all the variables4y+40=0We move all terms containing y to the left, all other terms to the right4y=-40y=-40/4y=-10_______________________________________________________3.1-3y=18We move all terms to the left:3.1-3y-(18)=0We add all the numbers together, and all the variables-3y-14.9=0We move all terms containing y to the left, all other terms to the right-3y=14.9y=14.9/-3y=-4+2.9/3
