y=7
Step-by-step explanation:
To solve the equation, we want to find out what y is. In order to do this, we have to get y by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
6y+3=45
3 is being added to 6y. The opposite of addition is subtraction. Subtract 3 from both sides.
6y+3-3=45-3
6y=45-3
6y=42
6 and y are being multiplied (6*y=6y). The opposite of multiplication is division. Divide both sides by 6.
6y/6=42/6
y=42/6
y=7
Let's check our solution. Plug 7 in for y in the original equation.
6y+3=45
y=7
6 (7) + 3=45
42+3=45
45=45
Both sides of the equation are the same, so we know our solution is correct.
