-y+y+30=0

To solve the equation \(-y + y + 30 = 0\), you can simplify the left side first. The terms \(-y\) and \(y\) cancel each other out: \[ -y + y = 0 \] So the equation simplifies to: \[ 0 + 30 = 0 \] Which is: \[ 30 = 0 \] This statement is false, indicating that there is no solution to the equation. The original equation is inconsistent for all values of \(y\). Thus, the solution set is empty, or you can say that there are no values of \(y\) that satisfy the equation.
