solve .08x + .12(260- x} = 48x, etc

[JOHNSBABYGIRL]

no idea where to begin

1) clear parentheses and simply -5m-(2m-4)+5

2) solve 2(3-2x) =x-4

3) solve -2k -3(4-2K) = 2 (k - 3) +2

4) solve 1/3x + 1/2x = 1/6x,

5) solve 2r -3/7 + 3/7 = -r/3

6) solve .08x + .12(260- x} = 48x

7) solve 3x - 5(x+4} + 9 = -11 + 15x

You posted 7 equations; this is not a "do your homework" site.

WHY have you got no idea where to begin? Skipped math classes?
