Answer:
a is 2x+2x and 4x
b is 6(7y-4) and 6*7y-6*4
Answer:

Step-by-step explanation:
First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.
Then, cross-multiply. 11 × 8 = 88, so
becomes
. 3 × 4 = 12, so
becomes
.
Now, you can subtract. 
Finally, simplify.
. The final difference is
.
10 more than (+ 10) a number (x) is greater than (>) 50
x + 10 > 50
To solve, subtract 10 from both sides.
x > 40
