Answer 1

Answer:

thank me and brainlist me

Step-by-step explanation:

but also the complete step by step method for solving your equations 2x+3y=4;2x-5y=-12 so that you understand better. ... 2 x +3 y =4;2 x −5 y =−12.

Answer 2

Step-by-step explanation:

2x+5y=12,

2x=12-5y,

x=12-5y/2,

by substituting x value in second equation,

x+3y=7

(12-5y/2)+3y =7,

12-5y+6y/2=7,

12-5y+6y=14

12+y=14

y=2

x+3*2=7(substituting y as 2)

x=7-6

x=1
