Answer:
x= 1
Step-by-step explanation:
y= -2 + 1
3x - 2y = 5
substituting method:
substituting y= -2+1 in equ. 3x-2y=5
=> 3x - 2(-2 + 1) = 5
=> 3x +4 -2 = 5
=> 3x + 2 = 5
=> 3x = 5 -2
=> 3x = 3
=> x = 3/3
=> x = 1
<span><span>A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?
----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.

Solve for "x":
If amount of compound A is 4x = 255
