Question

Solve for x and y if 2x+3y=17 and 3x-2y=6

Answer 1

Answer:

$= > 2x + 3y = 17.........eq(1) \\ \\ = > 3x - 2y = 6 \: .............eq(2) \\ \\ solving \: eq.(1) \: and \: (2) \\ 6x + 9y = 51 \\ 6x - 4y = 12 \\ ..................... \\ = > 13y = 39 \\ = > y \: \: \: \: = 3 \\ \\ then \: from \: eq(2) \\ = > x = \frac{6 + 2y}{3} \\ \\ = > x = \frac{6 + 2 \times 3}{3} \\ \\ = > x \: = \frac{12}{ 3 } \\ = > x \: = 4$
