Solve the simultaneous equation<br> 3x + y = 8<br> x - 3y = 11
podryga [215]

Answer:

x = 7 / 2, y = - 5 / 2

Step-by-step explanation:

3x + y = 8 ------> equation 1

3 ( 3x + y = 8 )

9x + 3y = 24 ------> equation 2

x - 3y = 11 ------> equation 3

Add equations 2 & 3,

9x + 3y = 24

x - 3y = 11

_________

10x + 0 = 35

10x = 35

x = 35 / 10

x = 3.5

Substitute x = 3.5 in equation 1,

3x + y = 8

3 ( 3.5 ) + y = 8

10.5 + y = 8

y = 8 - 10.5

y = - 2.5

x = 3.5

= 35 / 10

x = 7 / 2

y = - 2.5

= - 25 / 10

y = - 5 / 2

HELP ME can't figure this out. Please help
malfutka [58]

Answer:

The answer to your question is: letter J is the right answer

Step-by-step explanation:

                                                    3x - 4y = 6

Solve for y                        

Add - 3x in both sides             3x - 3x - 4y = -3x + 6

Simplify                                     -4y  = -3x + 6

Divide by -4                             -4/-4 y = -3/-4 x + 6/-4

Simplify                                    y = 3/4x - 6/4

                                                 y = 3/4 x - 3/2
