Sure... a good example of that is when you have non-linear expressions in the system, like say for example a linear and a quadratic, like y = 4x and y = x².
recall that for a system of equations, where the graph of both equations intersect, is the solutions, check the picture below.

Step-by-step explanation:
<u>Step 1: Define</u>
2(x/4 + 8) = 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2 on both sides: x/4 + 8 = 9
- Subtract 8 on both sides: x/4 = 1
- Multiply 4 on both sides: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(4/4 + 8) = 18
- (Parenthesis) Divide: 2(1 + 8) = 18
- (Parenthesis) Add: 2(9) = 18
- Multiply: 18 = 18
Here we see that 18 does indeed equal 18.
∴ x = 4 is the solution to the equation.
