MCC6.EE.7 -----SOLVE EQUATIONS How do I solve one-step equations? (In 6th grade, these equations contain only one-variable.) MCC6.EE.7 -----SOLVE EQUATIONS

IMPORTANT INFO: INVERSE = OPPOSITE ADDITION AND SUBTRACTION ARE INVERSE OPERATIONS Adding and Subtracting “UNDO” each other Equations have two sides. To solve an equation, you need to get the variable alone on one side of the equal sign. (this is called isolating the variable)

ADDITION EQUATIONS (pg. 76): (1.) X + 54 = 90 (2.) 49 = 12 + y

SUBTRACTION EQUATIONS (pg. 79) (2.) 3 = x - 16

And equations with decimals? (2.) 4.5 + x = 8 (1.) a - 2.7 = 4.8

And equations with decimals?

ADDITION EQUATIONS (pg. 76) (6.) C + 38 = 54

SUBTRACTION EQUATIONS: Page 79 (3.) a - 13 = 18 (4.) 15 = y - 7 (6.) 39 = d - 2 (5.) n - 24 = 9
