Solve for \( r \) \( 8+4 r=9 r+r-10 \) \( r=\square \) Submit

Solve the equation \( 8+4r=9r+r-10 \). Solve the equation by following steps: - step0: Solve for \(r\): \(8+4r=9r+r-10\) - step1: Add the terms: \(8+4r=10r-10\) - step2: Move the variable to the left side: \(8+4r-10r=-10\) - step3: Subtract the terms: \(8-6r=-10\) - step4: Move the constant to the right side: \(-6r=-10-8\) - step5: Subtract the numbers: \(-6r=-18\) - step6: Change the signs: \(6r=18\) - step7: Divide both sides: \(\frac{6r}{6}=\frac{18}{6}\) - step8: Divide the numbers: \(r=3\) The solution to the equation \(8+4r=9r+r-10\) is \(r=3\).
