Answer:
1/2 + 8 is equivalent to 1/2 - (-8)
0.5 - (-8) is ALSO equivalent to 1/2 - (-8)
0.5 + 8 is another equation that is equivalent to 1/2 - (-8)
Step-by-step explanation:
1/2 and 1/3 are similar because 3/6 and 2/6 are similar. They are so close but not the same.
11.3x + 7.2 = 86.3
11.3x + 7.2 (-7.2) = 86.3 (-7.2)
11.3x = 79.1
11.3x/11.3 = 79.1/11.3
x = 7
7 is your answer
hope this helps
