Answer:
x=8
Step-by-step explanation:
To solve the equation, we want to find out what x is. In order to do this, we have to get x 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.
3x+6=30
6 is being added on to 3x. The opposite of addition is subtraction. Subtract 6 from both sides.
3x+6-6=30-6
3x=30-6
3x=24
x is being multiplied by 3. The opposite of multiplication is division. Divide both sides by 3.
3x/3=24/3
x=24/3
x=8
Let's check our answer. Plug 8 in for x in the original equation.
Original equation: 3x+6=30
Substitute 8 for x: 3(8)+6=30
3(8)+6=30
24+6=30
30=30
The statement above is true, so we know that x is equal to 8.
