Question

solve the following system of equations graphically. 2x+3y=8, x+4y+9

2x+3y=12, 2y-1=4

Answer 1

Represent this situation algebraically and graphically. Solution: Let the present age of Aftab be x years and her daughter age be y years ... (iii) 6x – 3y + 10 = 0 2x – y + 9 = 0. Solution: (i) 5x – 4y + 8 = 0 7x +6y – 9 = 0 ... (v) 2x + 3y = 12. Solution: (i) 3x + 2y= 5; 2x – 3y = 17. Since , equations are consistent. ...... 10a + 2(1) = 4
