... If a + b = 7, then by subtracting a from each side, b = 7 a. In step 2, Guillermo substituted a + 7 for b and he should have substituted 7 a. Cara solved the first equation for a by subtracting b from each side. So, a = 7 b. She then substituted for a in the second equation. ...

... to five and the right side of the equation also simplifies to five. Explain your thinking. The equation was y equals negative x plus five. At the point zero, five, x equals zero and y equals five. When we plug these values into the equation we find that the two sides of the equation are equal. For t ...
