Assignment: Solving Equations Worksheet (front due Friday) (back due Monday following break)

Solve. 8k + 7 – 3k = 11k + 193(c + 4) = -4(c + 11)

Solve. 3b = 4(b – 7)5x + 3 = -17

Solving with Equations with Decimals 0.3b = 0.4b – x + 3 = -1.7

Solve Equations with Decimals 0.8k = k c = 0.4c + 1

Solve Equations with Decimals 0.8k = k c = 0.4c + 1

Solve Equations with Decimals 0.09k = c = 0.4c

Solving with Equations with Decimals 0.3b = 0.4b – x + 3 = -1.7
