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.

lions [1.4K]
In this question the brackets aren't really necessary

so (4x + 11) + 7x is the same as 4x + 11 + 7x

so find an answer that has the same 3 terms, but just rearranged with brackets
