Question

9x+4y=14
-6x+y=20 what is the solution method

Answer 1

you try and i will check it

Answer 2

im confused

Answer 3

sorry

Answer 4

its okay to be confused but show me an attempt and how i will tell you where u are going wrong

Answer 5

multiply the second part by -4
9x+4y=14
24x-4y=-80
then
9x+4y=14
+ 24x-4y=-80

=32x=-64
=x=-64/32
x=-2


9(-2)+4y=14
-18+4y=14
4y=14+18
y =32/4
y=8

the answer is
x=-2
y=8

Answer 6

The process of above answer is wrong.Because if you want to multiply with -4 you need to do so in both the equations.better to solve the sum through substitution method.
y=20+6x........(1)
9x+4(20+6x)=14
or,9x+80+24x=14
or,33x=-66
x=-2
y=20-12=8
