10 To get the variable by itself, which number needs to be moved? 1) Solve t = 60To get the variable by itself, which number needs to be moved?-5To move the -5, you have to do the opposite operation. What operation will we use?division
11 1) Solve -5t = 60-5 -5t = -12-5(-12) = 60Draw “the river” to separate the equation into 2 sidesDivide both sides by -5SimplifyCheck your answer
12 4) Solve You don’t like fractions? Let’s get rid of them! “Clear the fraction”by multiplying both sides of the equation by the denominator.
13 4 · · 4 x = -48 4) Solve Draw “the river” Clear the fraction – multiply both sides by 4SimplifyCheck your answer4 · · 4x = -48
