Question

resolver :7x+8y=29
5x+11y=26

Answer 1

7x+8y=29
5x+11y=26

hacemos reduccion:

-5(7x+8y=29)................-35x-40y= -145
7(5x+11y=26)...............35x+77y=182
                                           37y=37........y=37/37...........y=1

si y=1

5x+11y=26
5x+11(1)=26
5x+11=26
5x=26-11
5x=15
x=15/5
x=3

solucion:

x=3                  y=1
