Question

4x-3y=10,2x+4y=5 solve by substitution method​

Answer 1

$4x - 3y = 10 \\ 4x = 10 + 3y \\ x = \frac{10 + 3y}{4}$

substituting the value of x in another equation

$2x + 4y = 5 \\ 2 \times ( \frac{10 + 3y}{4} ) + 4y = 5 \\ \frac{10 + 3y}{2} + 4y = 5 \\ \frac{10 + 3y + 8y}{2} = 5 \\ 10 + 11y = 10 \\ 11y = 10 - 10 \\ 11y = 0\\ y = 0$

and x will be

$2x + 4y = 5 \\ 2x + 4 \times 0 = 5 \\ 2x = 5 \\ x = \frac{5}{2}$

Answer 2

it's ur answer x=2 ;y=4
