Select ALL expressions that are equivalent to -6. * -7 + 13

-10 - (-4)

26 - 32

16 - 10

3 - ( - 3)

Only the 2nd and 3rd expressions are equal to -6

Step-by-step explanation:

The only way to do this is evaluating ot actually doing each expression:

Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.

The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.

Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!
