It says:
Tell whether the given value of the variable is a solution of the equation. 108 = -36z; z = -3
Would it be -72z = -3 w/ a line through the = sign???

What about:
27 = n - 16; n = 11
Same directions but I tried 11 x 27....Is that right???

if z=-3, then plug -3 into the equation.
108=-36 (-3)
a neg times a neg = a positive. and 36*3=108, therefore -3 is a solution.

For the first problem the answer is yes. The given value is a solution of the equation 108=-36z where z=-3. If you replace the variable with -3 you get 108. But with the second equation.

you put -3 in the place of z so it would be -36 times-3
so 108 = 108 or 1=1

plug the -3 into the equation where the "z" is and multiply it out.
108=(-36)(-3)
108=108, so yes, it is a solution of the equation

"Does -3 X -36=108? The answer is yes.

The given value of the variable is -3. -3 times -36 is positive 108 therefore the given value is a solutiont of the equation....

No...
I think it would read like this...
108 = -36 x -3
108 = 108
So, the answer would be YES, the value of the variable (-3) is the solution...

plug in the -3
108=-36(-3)
108=108

yes, -36*-3= 108
soooo...
108= -36z
you are correct!
you wouldn't want to put a slash through the = sign!
good luck, sorry if this doesn't make any sense! i tried!
