Solve one-half minus π¦ equals three-fourths for π¦.

First things first, copy down the equation. If we wanna isolate π¦ and solve for π¦, weβll need to move everything else to the other side of the equation by subtracting one-half on the left and one-half on the right. Positive one-half minus one-half cancels out. That equals zero.

The left side now says negative π¦. And on the right side, we need to subtract one-half from three-fourths. We can rewrite one-half as a fraction with the denominator of four. Two over four is the same thing as one-half. Three-fourths minus two-fourths equals one-fourth. Negative π¦ equals one-fourth.

But weβre looking for positive π¦. And that means we can multiply both sides by negative one. Negative one times negative π¦ equals positive π¦. And one-fourth times negative one equals negative one-fourth.

π¦ equals negative one-fourth.
