Samuel is solving an equation for y . His first step is to add 7 to both sides. Which equation is he solving?(1 point)
Responses
2y + 7 = 15
2 y plus 7 equals 15
2y − 15 = 7
2 y minus 15 equals 7
2y + 15 = 7
2 y plus 15 equals 7
2y − 7 = 15
2y - 7 = 15
Samuel is solving the equation 2y - 7 = 15.
To determine which equation Samuel is solving, we can analyze his first step. He adds 7 to both sides of the equation.
Let's examine each option to see which one matches Samuel's step:
1. 2y + 7 = 15: In this equation, Samuel needs to subtract 7 from both sides to isolate y, not add 7.
2. 2y - 15 = 7: In this equation, Samuel needs to add 15 to both sides, not subtract 15.
3. 2y + 15 = 7: In this equation, Samuel needs to subtract 15 from both sides, not add 15.
4. 2y - 7 = 15: In this equation, Samuel can add 7 to both sides to simplify it further.
Based on the explanation, Samuel is solving the equation 2y - 7 = 15.
