Question

solve this question by elimination method 3 X + 2 Y = 7, 2 x minus 5 equal minus 8 give my answer please​

Answer 1

HEYA !!!

3x + 2y = 7 --- 1.

&

x - 5 = -8

Multiplying by 3

3x - 15 = -24 ---- 2.

...

Now, by elimination method:-

Subtracting 1 from 2 ...

3x - 15 - (3x + 2y) = -24 - 7

3x - 15 - 3x - 2y = -31

-2y = -31 +15

-2y = -16

y = 16/2

y = 8

....

Now,

in equation 1.

3x + 2y = 7

3x + 2(8) = 7

3x = 7 - 16

x = -9/3

x = -3......
