Question

4x - 1
2.
= x + 7
Can someone help please?

Answer 1

19/3 =
`6(1)/(3)`

Explanation:

`4x -12= x+7\\Collect-Like-Terms\\4x-x =7+12\\3x=19\\Divide -Both-Sides-Of-The-Equation-By ; 3\\(3x)/(3) =(19)/(3) \\\\x = (19)/(3)\\ \\x = 6.3\\`

Answer 2

6
`(1)/(3)`

Explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6
`(1)/(3)`

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13
`(1)/(3)` = 13
`(1)/(3)` in the end.

Hope this helps :)
