Algebra 5x-2y=1 2x+y=4

Mathematics
1 answer:
Zarrin [17]4 years ago
5 0

Answer:

(1,1)

Step-by-step explanation:

5x-2y=1

2x+y=4

Im gonna use substitution but you could also use elimination

2x+y=4

-2x     -2x

y=-2x+4

replace y in the first equation with the second equation

5x-2(-2x+4)=1

distribute -2

5x+4x-8=1

add

9x-8=1

   +8  +8

9x=9

divide both sides by 9

x=1

then put x in for the equation fo your choice im gonna use the second one

2(1)+y=4

2+y=4

-2    -2

y=1

Hope this helps :))

Solve the following simultaneous equations. Give your answer in the form a + b√3, where a and b are rational.
Savatey [412]

x + y = 3 -------------- i  x2

2x - √3y =  5 ---------ii x1

Subtracting eq ii from i

   2x + 2y = 6

-   2x - √3y =  5

-------------------------

        2+ √3y = 1

               y = 1/ 2+√3

                  = 2- √3y

6 - 6x = 5x – 9x - 8 .<br> The value of x is?
sergey [27]

Answer:

x=7

Step-by-step explanation:

6 - 6x = 5x – 9x - 8

Combine like terms

6-6x = -4x-8

Add 6x to each side

6-6x+6x =-4x-8+6x

6 = 2x-8

Add 8 to each side

6+8 = 2x-8+8

14 = 2x

Divide each side by 2

14/2 =2x/2

7 =x
