    A graph can be used to show the solution for a system of two linear equations ... You solve one equation for one variable and then substitute this expression into ... Problem. Solve for x and y. y = 3x + 6. - 2x + 4y = 4. y = 3x + 6. - 2x + 4y = 4 ... x = 5. Simplify and solve the equation for x. 3x + y = 19. 3 (5) + y = 19. 15 + y = 19.
