x/a + x/b = 1
Taking x as a common factor: x*(1/a + 1/b) = 1
Adding the fractional parts x*(b/ab + a/ab) = 1
or x*[(b + a)/ab] = 1
Multiply both sides by (a+b)/ab
x = (a+b)/ab
Another Approuch:-
x/a+x/b = 1
Multiply all terms by ab to eliminate the fractions:
bx+ax = ab
Factorise:
x(a+b) = ab
Divide both sides by (a+b):
x = ab/(a+b)
Because it is "solved for x", x will be by itself on one side of the equation. On the other side will be what x equals.
Solving a one variable linear equation involves getting the variable on one side of the equals sign by itself. To do this one uses the properties of numbers.
" y equals 4 equals 3 " is a mathematically meaningless statement, that doesn't lend itself to any standard operations or productive discussion.

That equation has no solution. There is no possible number that's equal to 18 more than itself.

-2x + 8 = 7x - 10 is technically an equation, in and of itself.

There is no "answer", X=6 is complete in itself. There is nothing to solve. What is the value of X? Well, it's equal to 6.
That equation has no solution. There is no possible number that's equal to 18 more than itself.
Nobody can help you find a solution until you get another equation to go along with this one. Your equation has two variables in it ... 'x' and 'y' ... so it has no unique solution all by itself.
This equation is unsolvable as x2 cannot be a negative number as would be suggested by this equation. Any number, even a negative, multiplied by itself will always give a positive number but this equation leaves you with x2 = -48
No. There is not enough information in the equation x + 2y = 2, by itself, to solve it. There are an infinite number of solutions. A second equation, or information to allow a second equation to be derived, must be given to find a solution.
y+9=14 subtract 9 from each side to get y by itself y=5
