Question 59256: If one-half of one integer is subtracted from three-fifths of the next consecutive integer, the difference is 3. What are the two integers?
I wrote for following expressions:
a =
b = a+6
c = 3(a+b)-4
I am unable to solve for the three angles. Your help is appreaciated.
Thank you.

You have 3 unknowns
That means you need 3 equations, or you can't solve.
The one you're missing is:
a + b + c = 180 That's true of all triangles
[1]
[2]
[3]
expand [2]
subtract c from both sides
[4]
add 4 to both sides
multiply both sides of [3] by 3
subtract one from the other
substitute in [4]
[5]
[1]
muiltiply both sides by 3
add to [5]
[3]
check
[1]
[2]
OK
so,
a = 20 degrees
b = 26 degrees
c = 134 degrees
