Sagot :
Answer:
x=2,y=2
Step-by-step explanation:
3y-1 = 5
or, 3y = 5+1
or, y = 6/3
y = 2
2x+1 = 3y-1
or, 2x = 3×2-1-1
or, 2x = 4
or, x = 2
[tex]\\ \sf\longmapsto \left[{2x+1\atop 2x+x}\:\:\:{3y-1\atop 3}\right]=\left[{3y-1\atop 4}\:\:\;{5\atop 3}\right][/tex]
[tex]\\ \sf\longmapsto 3y-1=5[/tex]
[tex]\\ \sf\longmapsto 3y=5+1[/tex]
[tex]\\ \sf\longmapsto 3y=6[/tex]
[tex]\\ \sf\longmapsto y=2[/tex]
Put the value in 1st one
[tex]\\ \sf\longmapsto 2x+1=3y-1[/tex]
[tex]\\ \sf\longmapsto 2x+1=3(2)-1[/tex]
[tex]\\ \sf\longmapsto 2x+1=6-1[/tex]
[tex]\\ \sf\longmapsto 2x+1=5[/tex]
[tex]\\ \sf\longmapsto 2x=5-1[/tex]
[tex]\\ \sf\longmapsto 2x=4[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{4}{2}[/tex]
[tex]\\ \sf\longmapsto x=2[/tex]
