Solve 3x - 5y = 17 9x - 15y = - 4

x = 5y 3 + 173 x = 5⁢y 3 + 173 9 (5y 3 + 173) - 15 y = - 4 x = 5y 3 + 173 x = 5⁢y 3 + 173 9x - 15 y = - 4

x = 5y 3 + 173 x = 5⁢y 3 + 173 51 = - 4

x = 5y 3 + 17 3 there is no solution

Solve for x in the first equation. x = 5y 3 + 173 x = 5⁢y 3 + 173 9x - 15 y = - 4 9⁢x - 15 ⁢y = - 4 Replace all occurrences of x with the solution found by solving the last equation for x. In this case, the value substituted is 5y 3 + 173 5⁢y 3 + 173. x = 5y 3 + 173 x = 5⁢y 3 + 173 9 (5y 3 + 173) - 15 y = - 4 9⁢ 5⁢y 3 + 173 - 15 ⁢y = - 4 Solve for y in the second equation. No Solution
