Question

A) Oliver in correctly solve the equation 2X +4 equals 10 he says the solution is X = 7

What is the correct solution



What mistake my Oliver have made

Answer 1

The correct answer is X=3

Answer 2

The correct solution is
`x=3`

He may have added 4 to both sides instead of subtracting 4 to both sides

Explanation:

2
`x`+4=10 subtract 4 from both sides which makes it

2
`x`=6 because 10-4=6 and 2
`x`+4-4=2
`x`

Now you have to divide both sides by 2 to get the
by itself

2
`x` divided by 2 is
`x` and 6 divided by 2 is 3

Which means
`x` equals 3
