Exercise 4.2.13 4.2. 13. Solve the system by substitution. {y = −2x + 5 y = 12x { y = − 2 x + 5 y = 1 2 x. Answer. Substitute 1 2 x 1 2 x for y in the first equation. Replace the y with 1 2 x 1 2 x. Solve the resulting equation.

Remember in the example y = 1 2 x + 3, we carefully chose values for x so as not to graph fractions at all. If we solve the equation 2 x + y = 3 for y, it will be easier to find three solutions to the equation. The solutions for x = 0, x = 1, and x = −1 are shown in the Table 4.13. The graph is shown in Figure 4.9.

Answer: 3x + 5 = 8. Ax + By = C. Since the system has infinitely many solutions, the values of A, B, and C must all be the same multiple of 3, 5, and 8, respectively. The two equations represent a single line, so the coefficients and constants of one equation must be a multiple of the other.
