Substitution method
y = x + 3 (*)
y = 3x + 1 (**)
Substitute (*) to (**):
3x + 1 = x + 3 <em>subtract 1 from both sides</em>
3x = x + 2 <em>subtract x from both sides</em>
2x = 2 <em>divide both sides by 2</em>
<h3>x = 1</h3>
Put the value of x to (*):
y = 1 + 3
<h3>y = 4</h3><h3>Answer: x = 1 and y = 4 → (1, 4).</h3>
