This equation has no solutions....0 solutions 3. Y=2 that's your answer: Times it by 4: 3y+10 = 2y*4 3y+10 = 8y
Move the 12y over to the other side: 10 = 8y - 3y 10 = 5y
Divide both sides by 5: 10/5 = 5y/5 2 = y 4. The equation has many solutions 5. Distribute the 4: 4z - 20 + 2 = 4z - 18 Subtract 4z -20 + 2 = -18 -18 = -18 This is true so that means there are infinite number of solutions and z could be anything Hope this helps!
