Adding and Subtracting Integer Equations Equation: maths statement that says two amounts argon meet Solution: when a changeable makes an equation true Ex. a + 23 = 82 if a = 59Determine if the esteem is a solution. (Plug 59 in for a)59 + 23 = 8284=82 No, non a solution. Ex. h + 12 = 27 if h = 15Determine if the time value is a solution. 15 is a solution because 15 + 12 = 27 = 27 patch up Equations: when resolve an equation, you be resoluteness for the versatile star (letter). You do this by acquire the letter by itself on one status of the equals sign. check these go to solve: 1. maneuver a extend border down the middle of the equal sign (now you set nearly two situations to the equation). 2. Circle the variable (letter). 3. adjust an arrow oer the number that needs to be moved in revise for the letter to be by itself. 4. Do the opposite carrying into attain to the arrowed number. 5. Do the same subject to the other side of the specked profligate. 6. Bring everything down. Ex. h + 19 = -38 - 19 - 19 h = -57 Ex.

x (-11) = 42 +(-11) +(-11) h = 31 Combining equal Terms Like Terms: pulse ar desire numbers Variables be comparable variablesEx. 2x 2 + 4x = 12 The 2x and the 4x are like toll The -2 and 12 are like footing Ex. 3x + 4 + 2x + 5 x + 8x 2 4x = 8x + 7 *Be plastered to always look at the sign in waitress of the number so you inhabit whether to subtract or add. When solving equations with like legal injury, you moldiness get all of the like terms together and then solve the equation. Follow these stairs: Draw dotted line down the middle of equals sign seat symbols above like terms. Ex. heart, star, circle, etc. adjust all like terms together. (Remember, to move something from one side of the equals sign to the other, you must do the opposite...If you want to get a full essay, order it on our website: Ordercustompaper.com
