Answer:
-13 13/35
Step-by-step explanation:
5 4/7 * - 2 2/5
Change to improper fractions
5 4/7 = (7*5 +4) /7 = 39/7
2 2/5 = (5*2+2)/5 = 12/5
39/7 * -12/5 = -468/35
Change back to a mixed number
35 goes into 468 13 times with 13 left over
-13 13/35
So, 5 x (-3) + 7 = -15 + 7 = - 8 , but not 4;
Then, -3 is not a solution to 5x + 7 = 4;
