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.
Okay, so
a=2b+11
<span>a+b = 2(a-b) </span>
<span>now solve </span>
<span>a+b = 2a-2b </span>
<span>3b = a, put that into the 1st equation: </span>
<span>3b = 2b+11 </span>
<span>b=11 </span>
<span>a = 2(11) +11 = 33 </span>
<span>check in the 2nd equation: </span>
<span>33+11 = 2(33-11) </span>
<span>44 = 2(22) </span>
<span>44 = 44</span>

Answer:
yes
Step-by-step explanation:
13-7=6 so that's the difference
12.75 - 11.25 = 1.50
11.25 - 9.75 = 1.50
there is a difference of $ 1.50 in allowance between brothers
that means the 7 yr old is gonna get : 9.75 - 1.50 = 8.25 <==
12.25x + 8.75y > = 90 (thats greater then or equal) <== ur inequality
Since 17 isnt a factor of 42 the only factor is 1
