Solve for d. 10d - 6d = 4 d = ____

Combine like terms: Combine like terms on the left side of the equation. We have 10d and -6d, which are like terms because they both contain the variable d. To combine them, we subtract 6d from 10d. Calculation: 10d - 6d = 4dIsolate the variable: Isolate the variable d. To find the value of d, we need to isolate it on one side of the equation. Since we have 4d = 4, we can divide both sides of the equation by 4 to solve for d. Calculation: 4d / 4 = 4 / 4Solve for d: Solve for d. After dividing both sides by 4, we get d = 1. Calculation: d = 1

____

Combine like terms: Combine like terms on the left side of the equation. $\newline$ We have $10d$ and $-6d$ , which are like terms because they both contain the variable $d$ . To combine them, we subtract $6d$ from $10d$ . $\newline$ Calculation: $10d - 6d = 4d$
Isolate the variable: Isolate the variable $d$ . To find the value of $d$ , we need to isolate it on one side of the equation. Since we have $4d = 4$ , we can divide both sides of the equation by $4$ to solve for $d$ . Calculation: $\frac{4d}{4} = \frac{4}{4}$
Solve for d: Solve for d. $\newline$ After dividing both sides by $4$ , we get $d = 1$ . $\newline$ Calculation: $d = 1$
