`a)` `x-3=5`
`x=5+3`
`x=8`
`y+2=-1`
`y=-1-2`
`y=-3`
Vậy \(\left(x;y\right)=\left(8;-3\right)\)
`b)`
`x-3=5`
`x=5+3`
`x=8`
`y+2=1`
`y=1-2`
`y=-1`
Vậy \(\left(x;y\right)=\left(8;-1\right)\)
\(a, x-3=5 \)
\(x=5+3\)
\(x=8\)
\(y+2= -1\)
\(y=-1-2\)
\(y= -3\)
\(------------\)
\(b, x-3=5\)
\(x=5+3\)
\(x=8\)
\( y+2= 1\)
\(y=1-2\)
\(y=-1\)
`x - 3 = 5`
`x = 5 + 3`
`x = 8`
`y + 2 = -1`
`y = -1 - 2`
`y = -3`
Vậy `x = 8, y = -3`
