HELP

Ari1234442:

7 - 3z - 4z = 28

supie:

Just solve it?

Ari1234442:

I keep on getting the wrong answer

mxddi3:

Ok, start by combining like terms. what is -3z + (-4z) ?

Ari1234442:

-7

mxddi3:

good, so now you have -7z +7 = 28 so then you subtract 7 from both sides. what is 28-7?

Ari1234442:

21

mxddi3:

yes, so now you have -7z=21. so divide both sides by NEGATIVE 7, and what do u get?

Ari1234442:

z=-3

mxddi3:

Yes, it's z=-3 Make sense?

Ari1234442:

Yes
