WebAlgebra. Solve by Graphing -7x-2y=14 , 6x+6y=18. −7x − 2y = 14 - 7 x - 2 y = 14 , 6x + 6y = 18 6 x + 6 y = 18. Add 7x 7 x to both sides of the equation. −2y = 14+7x - 2 y = 14 + 7 x. 6x+6y = 18 6 x + 6 y = 18. Divide each term in −2y = 14+7x - 2 y = 14 + 7 x by −2 - 2 and simplify. Tap for more steps... y = −7− 7x 2 y = - 7 - 7 x 2. Web(iv) 3x + y = 19. 3x – y = 23 (v) 3x + 7y = 4. x + 2y = -1 (vi) 3x + y = 7. 5x + 3y = 12. Solution: (i) Given 5x + 7y + 2 = 0 and 4x + 6y + 3 = 0. Hence, x = 9/2 and y = -7/2 (ii) Given 5x + 2y = 3. 3x + 2y = 5. Hence, x = -1 and y = 4 (iii) Given 3x + 4y – 5 = 0. x – y + 3 = 0. Hence, X = 1 Y = – 2 (iv) Given 3x + y = 19. 3x – y = 23 ...
