### Solve, Using Cross-multiplication : 5x + 4y + 14 = 0 3x

Given equation are 5x + 4y + 14 = 0 and 3x = -10 – 4y Comparing with a 1 x + b 1 y + c 1 = 0 and a 2 x + b 2 y + c 2 = 0, We have a 1 = 5, b 1 = 4, c 1 = 14 and a 2 = 3, b 2 = 4, c 2 = 10. Now, x = `[ b_1c_2 – b_2c_1 ]/[ a_1b_2 – a_2b_1 ] and y = [ c_1a_2 – c_2a_1 ]/[ a_1b_2 – a_2b_1 ]`

### If x²=4x+5y and y²=5x+4y, what is x= and y=? – Applied

Mar 30. ·. The two equations are mirror images of each other. Therefore, x must equal y where they intersect. Substituting x for y in equation 1, x^2 = 4x + 5x = 9x. Therefore x = 9. And therefore y = 9. Check 9^2 = 5*9 + 4*9 Therefore 81 = 45 + 36 = 81 check. Also x = y = 0 is a solution.
