Adding and Subtracting Integer Equations Equation: math statement that says two amounts are cope with Solution: when a versatile makes an equation authentic Ex. a + 23 = 82 if a = 59Determine if the value is a solution. (Plug 59 in for a)59 + 23 = 8284=82 No, not a solution. Ex. h + 12 = 27 if h = 15Determine if the value is a solution. 15 is a solution because 15 + 12 = 27 = 27 resolve Equations: when resolve an equation, you be solving for the inconsistent (letter). You do this by getting the letter by itself on one status of the equals sign. Follow these go to solve: 1. pull away a extend line down the middle of the equal sign (now you set about two sides to the equation). 2. Circle the variable (letter). 3. adjust an arrow over the number that needs to be moved in revisal for the letter to be by itself. 4. Do the opposite carrying in to action to the arrowed number. 5. Do the same social occasion to the other side of the dotted line. 6. Bring everything down. Ex. h + 19 = -38 - 19 - 19 h = -57 Ex.

x (-11) = 42 +(-11) +(-11) h = 31 Combining Like wrong Like Terms: meter are desire numbers Variables are alike variablesEx. 2x 2 + 4x = 12 The 2x and the 4x are like toll The -2 and 12 are like ground Ex. 3x + 4 + 2x + 5 x + 8x 2 4x = 8x + 7 *Be sealed to always calculate at the sign! in await of the number so you know whether to subtract or add. When solving equations with like cost, you must get all of the like terms unitedly and then solve the equation. Follow these steps: Draw dotted line down the middle of equals sign Put symbols in a higher place like terms. Ex. heart, star, circle, etc. Put 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: BestEssayCheap.com
