Question

Olve the two-step equation and identify the steps.

2 = − 7
4
+ 1
4
x

Answer 1

x = 5.142

Explanation:

2=-74+14x

if you want to make x the subject (work out its value), you need to single out x

1) the first thing that we can do is get rid of the -74

2) do this by adding it on to both sides of the equation. This is called the inverse

2+-74=-72 -74+14x=14x

-72=14x

3) to get x on its own, we now need to get rid of the 14

REMEMBER: 14x = 14×x

4) We do the inverse by dividing both sides by 14

-72÷14=-5.142...

its surprising that its not an integer

5.142=x

x=5.142

PLEASE LET ME KNOW IF THIS IS CORRECT
