Correct answer: A) A = the card is red, B = the card is black

5x-2y=11 and 3x+4y=4<br>Find the value of x and y in equation.

nadya68 [22]

5x-3y=11---(1)
3x+4y=4---(2)

(1)×3 and (2)×5

15x-9y=33-(3)
15x+20y=20-(4)

Subtract both

$\\ \sf\longmapsto -29y=13$

$\\ \sf\longmapsto y=\dfrac{-13}{29}$

Put in eq(1)

$\\ \sf\longmapsto 5x+\dfrac{-117}{29}=11$

$\\ \sf\longmapsto 5x=11+\dfrac{117}{29}=\dfrac{261+117}{29}=\dfrac{278}{29}$

$\\ \sf\longmapsto x=\dfrac{278}{145}$
