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}
