3x+y=52x-2y=-2solve by using process of elimination (find both x and y)​

Bingel [31]3 years ago

Answer:

The value of 'x' is 1 and 'y' is 2. So, the point is (1, 2).

Step-by-step explanation:

Given:

The given pair of linear equations are:

3x+y=5\\2x-2y=-2

In order to solve by elimination method, we have to eliminate any one variable using mathematical operations. Let us eliminate 'y'.

Multiplying the first equation by 2 and adding the result to the second equation. This gives,

(3x+y)\times 2=5\times 2\\6x+2y=10\\2x-2y=-2\\+\\----------\\8x+0=8\\8x=8\\x=\frac{8}{8}=1

Now, the value of 'y' can be calculated by plugging in 1 for 'x' in the first equation. This gives,

3(1)+y=5\\3+y=5\\y=5-3\\y=2

Therefore, the value of 'x' is 1 and 'y' is 2.

The solution is (1, 2).

7x2 +11x-6/7x2 - 10x + 3
velikii [3]

Answer:

Final result :

 x + 2

 —————

 x - 1

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   7 • 3 = 21  

Step-2 : Find two factors of  21  whose sum equals the coefficient of the middle term, which is   -10 .

     -21    +    -1    =    -22  

     -7    +    -3    =    -10    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  -3  

                    7x2 - 7x - 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   7x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (7x-3)  •  (x-1)

            Which is the desired factorization
