Question

3. Solve: 5x+6y=7 ; 3x+2y=5*​

Answer 1

by the elimination method:->

$\frac{5x + 6y = 7 \times multiplyby \: 3 \: \: }{3x + 2y = 5. \times multiply \: by5 \: } = > \frac{15x + 18y = 21}{15x + 10y = 25.} = > by \: subtracting \: \: \: \: \: 8y = \: - 4 \: \: \: = > \frac{ - 4}{8} = y. \:\: => as \: y = \frac{ - 1}{2} also \: \frac{1}{2} .$

$so \: gy \: putting \: it \: in \: equation \: 1 \: we \: get \: 5x + \frac{6}{2} = 7 = > 5x + 3 = 7.$

$5x = 7 - 3$

$5x = 4$

$x = \frac{4}{5} .$

mark it as a brainlist answer.
