Answer: 4/3
Step-by-step explanation:
First off, we should all get the denominators to be the same.
14 is the LCM of each of the denominators, so:
3x / 7 times 2/2 = 6x/14
-1/2 times 7/7 = -7/14
and 1/14 is 1/14
So now we have
6x/7 + -7/14 = 1/14
We can multiply everything by 14 to get rid of the denominator completely, which leaves us with:
6x - 7 = 1
Then we just solve like a normal equation:
6x = 8
x = 8/6 , or 4/3
Subtract 5x and add 3y from the left side so that it can be moved to the right side. This will allow you to solve and get the second equation.
Answer: 16
Step-by-step explanation:
multiply -4 onto (3-6) and set 8÷2 off to the side for now
-4(3-6)
-12+24 combine them
12 then solve 8÷2 which is 4
12+4 = 16
