Question

To solve simultaneous equation on calculator we press mode 5 and then 1 so what are the values of a,b,c
I.e A is the constant,coefficient of x or coefficient of y?

Answer 1

this really depends on what calculator you are using but using a casio fx-991ES gives you

ax + by = c
making a the coefficient of x

Answer 2

can you type out what you get on your calculator when you press mode 5, 1?

Answer 3

My calculator is Casio fx-991ES plus
It's like this
a b c
1(0 0 0)
2(0 0 0)




In place of 0 we have to place value

Answer 4

hm. do they give you an equation to solve?

Answer 5

Yea I got 2 equations to solve simultaneously
6x+3y=9 and other one is
5x+2y=4
I put the value as you said a= coefficient of x etc
And got x=-2
And y=7

Answer 6

yeah that should be the solution

Answer 7

so basically filling in the a b c values we get

a b c
1(6 3 9)
2(5 2 4)

using the values from equations 1 and 2

Answer 8

Yes

Answer 9

Thank you 👍🏻
