Hey there!
1/6x + 3/4y = 4
1/6(-1) + 3/4y = 4
- 1/6 + 3/4y = 4
3/4y - 1/6 = 4
ADD 1/6 to BOTH SIDES
3/4y - 1/6 + 1/6 = 4 + 1/6
SIMPLIFY IT!
3/4y = 4 + 1/6
3/4y = 25/6
MULTIPLY 4/3 to BOTH SIDES
3/4y * 4/3 = 25/6 * 4/3
SIMPLIFY IT!
y = 25/6 * 4/3
y = 50/9
y = 5 5/9
Therefore, the answer should be:
y = 5 5/9
Good luck on your assignment & enjoy your day!
