Math Addition
In addition, the method is to use mathematics to solve problems?

How to add: 16) times the +5 y =- 11, x-ray 2y = 11 22) 2 times = 2 - y with + Y =- 1 for correct times?? Please help me! Thank you!

, As well as dealing with any problem you like them To address these problems, handle. However, we each The same factor in the equation before we add together Which must be at least one term. So, a question 16th equation can multiply the 3x zoom - 6y = 33 (I Just 3) Now, we can compare the two equations : If we 3X + 5y = -11 times - 6y = 33 "" To add these equations Multiplying the entire equation, no variable was canceled. Then the boat -1 Multiplied by the second equation + 5y = -11 - 3 times the term x + 6y = -33 Now Cancellation after () 11 y a = - 44 y = -4 to add (just the original time Back in the equation for the sub-address and X) × = 3 번째 same You Can ask questions. I see the math is just this sort The first term of the equation 2x y () + y for a = 2 (Just a side y) Now, we can compare: a = 2x + y = 2x + y -1 multiplied by the additional -1 Second equation, 2x + y = a 2 - fold - y = 1 to add the. - X a = 3 = -3 (Next to the original equation) y = 8 and the lower x
