Exercise 22 Page 245

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

G

Practice makes perfect

To solve an equation, we should first gather all of the variables terms on one side of the equation and all of the constant terms on the other side using the Properties of Equality. In this case, we need to start by combining like terms.

5d+6-3d=12

SubTerm

Subtract term

2d+6=12

SubEqn

LHS-6=RHS-6

2d=6

DivEqn

.LHS /2.=.RHS /2.

d=3

This solution corresponds to the answer G.
