x - 7 - 9 = -3x - 16 = -3x = 13
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?

24-3x-273x=27+(-24)3x=3x=1
3x=12 3x/3=12/3 x=4
18 - 44x
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
-10
Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
x - 7 - 9 = -3x - 16 = -3x = 13

Subtract 3 from each side: -3x = 12Divide each side by -3: x = -4
24-3x-273x=27+(-24)3x=3x=1
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
you cant solve but you can simplify -55x
Baisiclyy 3x-1 3x-1 ____ 9x-1 then the answer is 8x :)
