Pls solve and show the steps, I'll give brainliest to whoever replies first and accurately

3(x-1) = 2x - y

3x-3 = 2x-y

3x-2x+y = 3

x + y = 3 > (1)

2(x+y) = 3+3y

2x + 2y = 3 + 3y

2x + 2y - 3y = 3

2x - y = 3 > (2)

make equation (1) and (2) together

x + y + 2x - y = 3+3

3x = 6

x = 2

now make x = 2 in equation (1)

x + y = 3

2 + y = 3

y = 3-2

y = 1

(x,y) = (2,1)
