Step-by-step explanation:

/ Solve equation [1] for the variable x

[1] x = y + 3

// Plug this in for variable x in equation [2]

[2] 3•(y +3) - 2y = 10

[2] y = 1

// Solve equation [2] for the variable y

[2] y = 1

// By now we know this much :

x = y+3

y = 1

// Use the y value to solve for x

x = (1)+3 = 4

Solution :

{x,y} = {4,1}

Answer:

x - y = 3 -  -  -  -  - (i) \\ 3x - 2y = 10 -  -  -  -(ii) \\ multiply \: 3 \: from \: eqution \: i \\ 3x - 3y = 9 -  -  - (iii) \\ from \: equaton \: (ii) nd \: iii \\  \\ y = 1 \\ put \: the \: value \: of \: y \: in \: equation \: i \\ x - 1 = 3 \\ x = 3 + 1 \\ x = 4
