4 x 7 = 30 - x.

What is the value of x?

x = 2

Step-by-step explanation:

Given

4 x 7 = 30 - x

First solve the left side. When you multiply, we have

28 = 30 - x

Combine like term. When - x crosses over equality sign, it becomes positive x, and 28 becomes - 28

So,

x = 30 - 28

x = 2

2

Step-by-step explanation:

4*7 = 28

28-30

x=2
