To subtract the expression \((5a + 1)\) from \((7a + 5)\), follow these steps:
-
Distribute the negative sign to the second expression: \[ (7a + 5) - (5a + 1) = (7a + 5) - 5a - 1 \]
-
Combine like terms:
- For the \(a\) terms: \(7a - 5a = 2a\)
- For the constant terms: \(5 - 1 = 4\)
-
Write the final result: \[ 2a + 4 \]
So, the result of \((7a + 5) - (5a + 1)\) is \(2a + 4\).
