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
