Question

it says determine how to rewrite one of the two equations above in the form ax + by=c. where a B and C are consistent so that the sum of the new equation in the unchanged equation from the original system results in an equation of one variable

Answer 1

-3x +4y = 24 (1)

6x +2y =-18 (2)

We can multiply equation (1) by 2 and we got:

-6x + 12y = 48

6x +2y =-18

_____________

14 y= 30

y = 30/14= 15/7

And the value of x would be:

x= 4y-24/3

x= (60/7 -24)/3
