Efficient way of solving the equations
<em>The efficient way of solving this problem is by solving for x in the first equation because it has a coefficient of 1;</em>
The evidence is shown as follows;
<em>Make x the subject of formula in equation 1</em>
<em>Substitute 1 + 3y for x in equation 2</em>
<em>Open bracket</em>
<em>Make y the subject of formula</em>
<em>Divide both sides by 23</em>
Recall that x = 1 + 3y
<em>Substitute 0 for y in the above expression</em>
Solving for y in the second equation will take more steps
