Question

solve 2x-3y=7 , 5x+2y=10 by elimination method​

Answer 1

Answer:

x=44/19,y=-15/19

Step-by-step explanation:

2x-3y=7---------------------------(1)

5x+2y=10-----------------------------------(2)

(1)x5-(2)x2

[10x-15y]-[10x+4y]=35-20

-15y-4y=15

-19y=15

y=-15/19

substitute in (1)

2x-3(-15/19)=7

2x+45/19=7

38x+45=133

38x=88

x=88/38=44/19
