Multiply (4) (7x8) and you’ll get 7/2
first you put 18/y=2
you multiply by 18 to get y=36
your answer is 36, y=36
If x= -5, then 3 - 2x = 13
The value of x from the given information is 2.72
<h3>Addition postulate</h3>
Given the following functions below
JD = 2x + 3y
DV=7-y
VN = 9x - 2y, and;
JN = 32
Using the addition postulate below;
JD+DV+VN = JN
Substitute the given parameters into the formula
2x+3y+7-y+9x-2y = 32
11x+2y-2y= 32- 7
11x = 25
x = 25/11
x = 2.72
Hence the value of x from the given information is 2.72
