Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x

(A. 46)
Step-by-step explanation:
STUDY CORRECTION.
5x+2y=7
7x-2y=5 its subtract not add
Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.
Explanation:
The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.
If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.
The given expression is,

Use multiplication property of equality, multiply 5 both sides,


Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.
There are 10 rows of 3 colums of "x"'s, so.. 3x10 or 30 "x"s, and we know that's 5/3 of the original... the original will be one whole or 3/3 or 1
thus

solve for "x"
