Question

solve for d. 10d - 6d = 4 d = submit

Explanation:

Step1: Combine like terms

First, we simplify the left - hand side of the equation \(10d - 6d=4\). Since \(10d\) and \(- 6d\) are like terms, we can combine them. According to the rule of combining like terms (for terms with the same variable, we add or subtract their coefficients), \(10d-6d=(10 - 6)d\). So, \(10d-6d = 4d\), and the equation becomes \(4d=4\).

Step2: Solve for d

To isolate \(d\), we divide both sides of the equation \(4d = 4\) by the coefficient of \(d\), which is 4. Using the division property of equality (if \(a\times x=b\), then \(x=\frac{b}{a}\) when \(a
eq0\)), we have \(d=\frac{4}{4}\).

Step3: Simplify the fraction

Simplifying \(\frac{4}{4}\), we get \(d = 1\).

Answer:

\(d = 1\)
