Step-by-step explanation:
The given expression is:
We need to solve it to make q the subject of the formula.
Cross multiplying both sides,
Adding 3r to both sides,
Now, dividing both sides by r,
Hence, this is the required solution.
Y=1/4x−2y=−2x+3 help solve problem.

Answer:
(x, y) = (2 2/9, -1 4/9)
Step-by-step explanation:
Equate the values of y and solve for x.
1/4x -2 = -2x +3
(2 1/4)x = 5 . . . . . . . . add 2+2x to both sides
x = 20/9 = 2 2/9 . . . multiply by 4/9
y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation
y = -1 4/9
The solution is x = 2 2/9, y = -1 4/9.
