Question

I'm stuck on these can someone help me and show the work please

Answer 1

7.) 4 (-2) 12 I multiply 4 by -2 which gives me
-8 = 12 so it is a no solution

8.) 39 - 3 = -6 (4-3)
first u want to multiply the -6 by four and the -6 by the -3 which gives you :
39 - 3 = -24 + 18
36 = -6
this is also a no solution
