Please help me! Sorry there are 4 questions I need to check my attempts with to see if I am on track. Thanks!!
1. 53[2(3x4)+3]
2. Evaluate when x = 3 and y = 2
3x squared  4y squared
_______________________
4x  7y
3. 3/4y = 24
4.
m + 1 5 2m  1
______ + ___ = ______
4 6 12

1. 53[2(3x4)+3]
Start from the inside and work outward.
5  3(6x  8 + 3) = 5  18x + 5 = 18x
2. (3x^2  4y^2)/(4x 7y) Just plug in the numbers and calculate. (x^2 = x squared online.)
3. Multiply both sides by 4/3.
4. From the way you express the equation, I don't know which numbers belong where.
(m + 1)/4 + 5/6 = (2m  1)/12?
