3x - 1/4y = -2 (1/4 is a fraction, solve for y)
1 answer:
Answer:
y = 12x + 8
Step-by-step explanation:
1. 3x - 1/4y = -2
Subtract 3x from both sides
2. -1/4y = -2 - 3x
The equation is in standard form.
3. -1/4y = -3x - 3
Multiply both sides by -4
4. Check photo for step 4
Divide by -1/4 = -0.25 undoes the multiplication -1/4 = -0.25
5. y = (-3x-2) / (-1/4)
Divide -2 - 3x by -1/4 = -0.25 by multiplying -2 - 3x by the reciprocal of -1/4 = -0.25
y = 12x + 8
