I don't understand any of this which is why I didn't pick answers for you guys to check.
You just have to remember that dividing a number by itself gives a quotient of 1. When it says "solve for x" that means you want to find the value of x all by itself.
SO, if you have
-6g = 42
You just need to divide by the -6 to get g all by itself. Since -6g = 42,
-6g/-6 = 42/-6
(-6/-6)g = -7
g = -7
Then you can check your answer by multiplying by -6 to make sure you get the same original values:
-6g = -6(-7) = 42.
#2 is the same, but instead of dividing, you multiply to get rid of the fraction
x/8 = 16
(x/8)*8 = 16*8
x(8/8) = 128
x = 128
#3 and 4 are just the same, using different numbers.
For #5, just replace every x with a 4 and see whether the statement is true.
5x=20
5(4) = 20
20 = 20
so, yes. x=4 is a solution to that equation.
