7(d-5)+12=5 Add 12 to -35 to get -23. 7d-23=5 Since -23 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 23 to both sides. 7d=23+5 Add 5 to 23 to get 28. Simplify the left-hand side of the equation by canceling the common factors $d=28 \over 7$ Simplify the right-hand side of the equation by simplifying each term answer d=4
