Step-by-step explanation:
<u>Step 1: Define Equation</u>
(7x - 1) + (13x - 19) = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 20x - 20 = 180
- Isolate <em>x</em> term: 20x = 200
- Isolate <em>x</em>: x = 10
<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>: (7(10) - 1) + (13(10) - 19) = 180
- Multiply: (70 - 1) + (130 - 19) = 180
- Subtract: 69 + 111 = 180
- Add: 180 = 180
Here we see that 180 does indeed equal 180.
∴ x = 10 is the solution to the equation.
The smaller number is 27 and the larger one is 119
