<em>Replace all occurrences of x with y + 3 in each equation.</em>
<em>Replace all occurences of x in 6x - 5y = 15 with y + 3.</em>
<em>6 (y+3) -5y = 15</em>
<em>x = y + 3</em>
<em>Simplify 6 (y + 3) - 5y.</em>
<em>Simplify each term.</em>
<em>Apply the distributive property.</em>
<em>6y + 6 · 3 - 5y = 15</em>
<em>x = y + 3</em>
<em>Multiply 6 by 3.</em>
<em>6y + 18 - 5y = 15</em>
<em>x = y + 3</em>
<em>Subtract 5y from 6y.</em>
<em>y + 18 = 15</em>
<em>x = y + 3</em>
<em>Move all terms not containing y to the right side of the equation.</em>
<em>Subtract 18 from both sides of the equation.</em>
<em>y = 15 - 18</em>
<em>x = y + 3</em>
<em>Subtract 18 from 15.</em>
<em>y = -3</em>
<em>x = y + 3</em>
<em>Replace all occurences with y with -3 in each equation.</em>
<em>Replace all occurences of y in x = y + 3 with -3.</em>
<em>x = (-3) + 3</em>
<em>y = -3</em>
<em>Add -3 and 3.</em>
<em>x = 0</em>
<em>y = -3</em>
