What is -7y= -91 I'm now learning coefficients and constants that my teachers won't help with when I have 2 math teachers
i hope this helps you
(-)÷(-)= +
-7y= -91 divided -7 two sides
-7y÷(-7)= -91÷(-7)
y=13
-7y=-91
You have to divide the -7 on both sides so you cancel out the -7 in front of the y........ then you will end up with y= -91 / -7
Then you divide the -91 by -7
