Question

how many solutions does this equation have? -4r - 4 = 4r - 8r + 15 no solution one solution infinitely many solutions

Explanation:

Step1: Simplify right - hand side

First, we simplify the right - hand side of the equation \(-4r - 4=4r - 8r + 15\). Combine like terms on the right - hand side: \(4r-8r=-4r\), so the equation becomes \(-4r - 4=-4r + 15\).

Step2: Add \(4r\) to both sides

Add \(4r\) to both sides of the equation \(-4r - 4=-4r + 15\). We get \((-4r+4r)-4=(-4r + 4r)+15\), which simplifies to \(-4 = 15\).

Answer:

no solution
