Okay I can do this!

Step-by-step explanation:

So we have to find the value of x.

So we will move 4x to left hand side (l.h.s)

Like this:

4x = 30 + 50

Further solving it.

4x = 80

Now, we want to find x so we will divide 4 on both the left hand side and right hand side as shown below.

4x / 4 = 80 / 4

4 cut by 4 equals to 1 since 4 x 1 = 4

80 cut by 4 equal to 20 as 4 x 20 = 80

1x = 20

(No need to write 1 with x as we have found the value)

∴ x = 20
