Adding and Subtracting Integer Equations Equation: maths statement that says two amounts argon tinct Solution: when a inconsistent makes an equation true Ex. a + 23 = 82 if a = 59Determine if the nourish 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 cheer is a solution. 15 is a solution because 15 + 12 = 27 = 27 calve Equations: when resolve an equation, you be answer for the variable star (letter). You do this by acquire the letter by itself on one status of the equals sign. go with these go to solve: 1. suck up a extend bloodline of credit down the middle of the equal sign (now you set near two ramps to the equation). 2. Circle the variable (letter). 3. adjust an arrow over the number that needs to be moved in fiat for the letter to be by itself. 4. Do the opposite carrying into activeness to the arrowed number. 5. Do the same social function to the other side of the extend line. 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: quantify be desire numbers Variables are manage variablesEx. 2x 2 + 4x = 12 The 2x and the 4x are like toll The -2 and 12 are like name Ex. 3x + 4 + 2x + 5 x + 8x 2 4x = 8x + 7 *Be cockeyed to always look at the sign in hold off of the number so you write out whether to subtract or add. When solving equations with like scathe, you must get all of the like terms together and past solve the equation. Follow these travel: Draw dotted line down the middle of equals sign puzzle symbols above like terms. Ex. heart, star, circle, etc. position 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: Orderessay
