Question

I appreciate any help. Trying to get the hang of these.

Answer 1

x = 12

Explanation:

Since the top line is equal to the bottom, you make the equation -

x + x + 4 = x + 16

You subtract an x on both sides because there is one on each side -

x + 4 = 16

Then you subtract the 4 from both sides to get x by its self, which makes

x = 12

Answer 2

X=12

Explanation:

This question can be answered in two ways:

Method 1

The length of the first line = x +x +4

The length of the second line = x +16

But both lines are equal, thus,

x +x +4 = x +16

2x +4 = x+16

2x - x =16-4

x= 12

Method 2

The mark for the first X in the two lines matches meaning they are equal.

Thus, we are left with

x + 4 = 16

x = 16 - 4

x =12
