Question

3a+4b=24 2a-2b=02. 8c+3d=46 4c+d=22. 3u+4v=19 2u+v=6​

Answer 1

Respuesta:

a= 4

b= 3

c= 5

d= 2

u= 1

v= 4

Explicación paso a paso:

3a+4b=24

2a-2b=02

3(1+b)+4b=24

b=3

a= 1+3= 4

8c+3d=46

4c+d=22

8c+3(22-4c)=46

c= 5

d=22-4.5 = 2

3u+4v=19

2u+v=6​

3u+4(6-2u)=19

u=1

v= 6-2.1= 4
