Question

need help with solving this system of equations

Answer 1

3x + 4y =8
-2x + 5y = 3

Answer 2

the struggle is real. i keep getting weird numbers.

Answer 3

u wanto solve all the way,
or u just wanto knw whether these have solutions or not ?

Answer 4

i have to solve all the way

Answer 5

ok, lets do it by elimination method

Answer 6

in elimination method,
first step is to make the x coefficients same for both equations

Answer 7

3x + 4y =8
-2x + 5y = 3


how do we make them same ?

Answer 8

okay... let me try and you correct me if this is wrong. so i do
5[3x + 4y =8]
-4[-2x + 5y =3]

is that right

Answer 9

that works !! keep going :)

Answer 10

you're eliminating y, i can see good :)

Answer 11

15x + 20y = 40
8x + -20y = -12

Answer 12

23x + 0y = 28

Answer 13

see now i have a weird number

Answer 14

get use to weird numbers

Answer 15

23x + 0y = 28

23x = 28

x = 28/23

Answer 16

x = 1.217

Answer 17

that is all it means, x is 28/23

Answer 18

now find y, by picking some equation, and substituting x = 28/23

Answer 19

i got y = 1.0875

Answer 20

Answer 21

good job !!

Answer 22

WEIRD

Answer 23

lol

Answer 24

id leave them in fraction part
x = 28/23
y = 25/23
