Question

Help. I will give a medal!!

Answer 1

4x + 9y = 21
3x - 8y = 1
What is the first step of eliminating the x?

Answer 2

i am doing it on note book so plz wait.

Answer 3

thanks :)

Answer 4

Divide the first with 4 or the second with 3 so that you have single x on both equations. Or you can multiply the first with 3 and second with 4

Answer 5

thank you wolfe.. so much.

Answer 6

and thanks Rina :)

Answer 7

3(4x=9y=21)
4(3x-8y=1)
12x+27y=63
12x-32y=4
59y=59
y=59/59
y=1

Answer 8

now atke any equation and solves for x so
4x+9y=21
4x+9(1)=21
4x+9=21
4x=21-9
4x=12
x=12/4
x=3
