Answer:
-5/8a - 2.8b
Step-by-step explanation:
-3/8a + 3.2b + (-6b) - 1/4a
=> -3/8a + 3.2b + (-6b) - 2/8a
=> -5/8a + 3.2b - 6b
=> -5/8a - 2.8b
Therefore, -5/8a - 2.8b is the solution to your problem.

Answer:
51 74
Step-by-step explanation:
x = smaller
x +23 = larger
added together (x + x+23) equal to 28 less than 3x = 3x-28
x + x+23 = 3x-28 subtract 2x from both sides of the equation
23 = x -28 add 28 to both sides
51 = x then the larger = 51 + 23 = 74
