Question

if 3x+2y=10 and 2x+3y=15 find the value of x+y ............please solve it's urgent and I will mark you as brainlist​

Answer 1

HERE IS UR ANSWER DEAR,

3x + 2y = 10--------(1)

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

(1)×3 ------9x + 6y = 30

(2)×2------4x + 6y = 30

by elimination method,

5x = 0

x = 0

sub/: x=0 in (1)

3(0) + 2y = 10

2y = 10

y = 10/2

y = 5

x+y = 0+5 = 5
