Solve for y.
y-1/y+1 = a-b/a+b

a. y=a/b
b. y=a-b/a+b
c. y=a+b/a-b

divide the numerator and denominator of right side of your equation to b then it would be (a/b)-1/(a/b)+1. so it becomes similar to left side. so y=a/b.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
