need a walk thru?

OpenStudy (anonymous):

If you dont mind @the_ocean_girl

OpenStudy (anonymous):

28, I believe.

OpenStudy (anonymous):

Sorry. Browser crashed. 70 = 28 is what I got.

Theoceangirl (the_ocean_girl):

You should get 70= 14+14z

OpenStudy (anonymous):

I'm honestly confused @the_ocean_girl Sorry

Theoceangirl (the_ocean_girl):

it's fine, math isn't easy

Theoceangirl (the_ocean_girl):

when you multiply -2z by -7, you get 14 but -2 is a coefficient of z so you have to carry the z over in your product

Theoceangirl (the_ocean_girl):

because it's not a regular -2, it's negative 2 multiplied by z and since you dont know z you carry it over until you can solve
