Answer:
y=0
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
1. Open the brackets
problem: 4.5y + 9 - 6.2 + 3.1y= 7.2y + 2.8
2. Combine like terms/solve for y
problem: 7.2y-4.5y-3.1y=-0.4y
-0.4y=9- 6.2 - 2.8=0
3. Solve/algebra
-0.4y=0
*-0.4 divided by zero is 0, (anything divided by 0 is 0!)
y=0
Cheers! Hope you understand this.
