Answer:

x = 5.8

Step-by-step explanation:

2x + 9.4 = 21

Subtract 9.4 on both sides.

2x + 9.4 = 21

-9.4 -9.4

2x = 11.6

Divide by 3 on both sides to isolate the variable.

2x/2 = 11.6/2

x = 5.8

The graph means that 2 x and 9.4 make up 20 in total, so set up the equation 2x + 9.4 = 20.

Subtract 9.4 from both sides.

2x = 10.6

Divide by 2.

x = 5.3

The answer is the value of x that makes this equation true is 5.3

Hope this helps
