Identify like terms: Identify like terms. In the expression, −(74)p, −(72)p, and 71 are the terms we are looking at. The terms −(74)p and −(72)p are like terms because they both contain the variable p with the same exponent (which is 1, though not written). The term 71 is not a like term with the others because it does not contain the variable p.
Combine like terms: Combine the like terms.To combine the like terms, we add the coefficients of −74p and −72p together.-\frac{\(4\)}{\(7\)}p + \left(-\frac{\(2\)}{\(7\)}p\right) = -\left(\frac{\(4\)}{\(7\)} + \frac{\(2\)}{\(7\)}\right)p\(\newlineNow, we add the fractions.
Add fractions: Add the fractions.When adding fractions with the same denominator, we simply add the numerators and keep the denominator the same.−(74+72)=−76So, −(74)p+(−(72)p) becomes −76p.
Write final expression: Write the final expression.Now we have the combined like terms and the constant term. We write them together to form the equivalent expression.−76p+71This is the simplified expression after combining like terms.
