Okay, so
a=2b+11
a+b = 2(a-b)
now solve
a+b = 2a-2b
3b = a, put that into the 1st equation:
3b = 2b+11
b=11
a = 2(11) +11 = 33
check in the 2nd equation:
33+11 = 2(33-11)
44 = 2(22)
44 = 44
a=2b+11
a+b = 2(a-b)
now solve
a+b = 2a-2b
3b = a, put that into the 1st equation:
3b = 2b+11
b=11
a = 2(11) +11 = 33
check in the 2nd equation:
33+11 = 2(33-11)
44 = 2(22)
44 = 44
Answer:
11 , 33
Step-by-step explanation:
Write out the equation
2x + 11 + x = 2(2x + 11 - x)
Simplify
3x + 11 = 4x + 22 - 2x
3x + 11 = 2x + 22
Solve for x
3x = 2x + 11
x = 11
Now we have x, find the other number
2(11) + 11 = 33
11 and 33 are the two numbers.
