Evaluate

8 d + 3 d

Collect like terms by calculating the sum or difference of their coefficients

(8 + 3) d

Add the numbers

11 d

11 d - 2

11 d - 2 = 42

Move the constant to the right-hand side and change its sign

11 d = 42 + 2

Add the numbers

11 d = 44

Divide both sides

\frac{11 d}{11} = \frac{44}{11}

Divide the numbers

d = \frac{44}{11}
