Question

I need some help guys !! Solve using substitution:
5y – x – 6 = 0
-3x + 6y = -9

Answer 1

Put one of those equations in terms of x, so rearrange terms so that x appears only on the left-hand side, then substitute this x-equation into the x variable in the second equation. Then you can solve for y. Once you know y, then solve for x.

Answer 2

how do we do that

Answer 3

firstly make one of the variable the subject say x in 5y-x-6=0
x=5y-6
then subtitute5y-6 in the 2nd equation
-3(5y-6)+6y=-9
that makes
-15y+18+6y=-9
then rearagnge to solve for y

Answer 4

then u can solve for x using y you have just solved for.

Answer 5

okay thanks
