CHAPTER 6, LESSON 1: SOLVE ONE-STEP EQUATIONS An equation is a mathematical sentence stating that two quantities are equal. x+2=6 The value of the variable is the solution of the equation. x=4 SOLVING AN EQUATION To solve an equation, first you have to get the variable alone on one side of the equal sign. This is called isolating the variable. x + 5 = -7 Use inverse -5 -5 operations! X = -12 Check if your answer is correct! k - 15 = 11 +15 +15 k = 26 X + 7 = -9 -7 X -7 = -16 11 = g + 16 -16 - 16 -5 = g 7 + y = 17 -7 -7 y = 10 -25 = -6 + m +6 +6 -19 = m USING A TAPE DIAGRAM An angelfish can grow to be 12 inches long. If an angelfish is 8.5 inches longer than a clownfish, how long is the clownfish? EXIT TICKET Solve each equation. Remember to check your solution! 1) 7 = y +2 2) q – 8 = -9 3) r – 4 = -2 4) -5 = b + 8
