Mark incorrectly solved the inequality -4(5/2+3/2x) > 8. His work is shown. Which step shows an error based on the inequality
aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

-4(\frac{5}{2}+\frac{3}{2}x)>8

Now solving this expression step by step.

First -4 distributed over parentheses.

(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8

Now solving bracket term, we get:

-10-6x>8

Now taking like terms together, we get:

-6x>8+10

-6x>18

-x>3

Now multiplying this expression by (-1), we get:

x>-3

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8
