Question

3x + 4y = 10 equation-1
2x-2y = 2 equation-2
solve by elimination method ​

Answer 1

$\huge{\boxed{\mathcal\pink{\fcolorbox{red}{white}{Answer}}}}$

Step-by-step explanation:

$3x + 4y = 10 - - - - (1) \\ 2x - 2y = 2 - - - - (2)$

Now multiply 2 in equation (2)

we get,

$2(2x - 2y = 2) \\ 4x - 4y = 4 - - - - (3)$

now eliminate equation (1) and (3)

$3x + 4y = 10 \\ 4x - 4y = 4$

___________________

$7x = 14 \\ x = 2$

now put the value of x in equation (1)

$3x + 4y =10$

$3 ×2 + 4y=10$

$y=1$

Answer 2

Step-by-step explanation:

(3X+4y=10)*2=>6X+8y=20

(2x-2y=2)*3=>6x-6y=6

by subtracting this balanced equations we get

14X=26

X=26/14
