Answer 1

x = (95*3)+15 = 300



Ok

Answer 2

Option C: x = 300

Explanation:

Step 1. Expand the brackets.

When factorising (putting into brackets) and expanding (taking out of brackets), it is always important to remember that the number on the outside multiplies everything on the inside. It is also important to remember the signs of the outside and inside numbers (i.e. if the numbers are positive or negative).

`(1)/(3)`(x - 15)

= (
`(1)/(3)` × x) - (
`(1)/(3)` × 15)

= (x ÷ 3) - (15 ÷ 3)

=
`(x)/(3)` - 5

Step 2. Solve the equation.

`(x)/(3)` - 5 = 95

What we want to do is to get x on its own on one side, so that we can figure out the value of x.

`(x)/(3)` - 5 = 95

+ 5 to both sides (do the opposite of what is there,
`(x)/(3)` is subtracting 5 right now, but we want to cancel that subtraction out, so we do the opposite of subtraction, i.e. addition)

`(x)/(3)` = 95 + 5

`(x)/(3)` = 100

× 3 to both sides (do the opposite of what is there: x is divided by 3 right now, but we want to cancel that division out, so we do the opposite of division, i.e. multiplication)

`(x)/(3)` x 3 = 100 x 3

x = 100 x 3

x = 300

Step 3. We look for out answer within the options given.

As we can see, the option of [x = 300] is option C, so the answer we would give would be "C".
