Question

What is the solution to the system of equations represented by the two equations? ]
y = 3/2x
y = -1/2x + 4
( , )

Answer 1

HI!!

Answer 2

solve \[\frac{3}{2}x=-\frac{1}{2}x+4\] for \(x\)

Answer 3

easier if you multiply both sides by 2 and start with \[3x=-x+8\]

Answer 4

add x to both sides, then divide both sides by 4

Answer 5

Put y=3/2x in second eqaution , then solve for x , after that u will get x .
Then put value of x in any above equation , u will get value of y ...
that will be ur solution (x , y)

Answer 6

3 divided by 4 = 0.75 and 8 divided by 4 = 4 so is it 0.75 for x and 4 for y?

Answer 7

no please check again ... first u have 3/2x = -1/2x +4
Then just multiply both sides by 2 , u will get 3x = -x + 8 okay ?

Answer 8

ummm XD

Answer 9

would it be X = 3 and 8 = y?

Answer 10

wait , we have got 3x = -x + 8
now can u move -x to left hand side ,,,? ( hint just add x to both sides)

Answer 11

yes?

Answer 12

So what do u get ?

Answer 13

4 = 4?

Answer 14

see the step here we have got 3x = -x + 8
now to move -x to left hand side we just add x to both sides
so we get 3x + x = -x +x +8
=> 4x = 8 okay?

Answer 15

oh ok

Answer 16

so x = 2?

Answer 17

Correct !!

Answer 18

Now just put this value x=2 in any above equation u will get y ..

Answer 19

ok!

Answer 20

1.5 * 2 = 3

Answer 21

Very good !!!

Answer 22

0.5 * 2 = 1 + 4 = 5 so umm

Answer 23

oh its -1/2 XD

Answer 24

So we have got (2 , 3)

Answer 25

ye its 3 :D thanks for the help

Answer 26

U r Welcome :)
