I didn't understand well the way you typed but I think that it is 7/3x + 2/x + x/x-1 , right? So the last common denominator is the one you can divide by all denominators and multiply by the nominator. So, it would be, if I understood well what you asked, 3x(x-1).
I’m sorry if I’m wrong but 4/36=7/8?
Answer:
7/30
Step-by-step explanation:
-3/9 * -56/80
-3/9= -1/3
-56/80 = -7/10
-1/3(-7/10)
1(7) / 3(10)
7/30 or 0.2333
Answer:
x = 18
Step-by-step explanation:
Subtract 5 on both sides:
-2x + 5 =- -31
-5 -5
-2x = -36
Divide by -2 on both sides:
-2x = -36
/-2 /-2
x = 18
