First lets set up the equation.
12 - 7b + 10b = 18.
Now lets combine all like terms on the left hand side.
12 - 7b + 10b = 18
12 + 3b = 18
Now lets combine all like terms using the like terms on the left side and on the right side.
12 + 3b = 18
-12 -12
3b = 6
Now lets divided (since the 3 is being multiplied to the b).
3b/3 = 6/3
So your final answer is:
b = 2
6
6
15x minus 8=minus 180 3x+8=24
X=-3
The Answer to this question is 9 (2B+4) and (1B+3)
6
I'll do ya one better - 12 plus 8 equals what?
6
6
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
15x minus 8=minus 180 3x+8=24
12-3(2+15) = -39
Seventy plus negative 12, or seventy minus 12 (same thing) is equal to 58.
What minus 6 equals 12 is 18
That will depend on the plus or minus value of 12 which has not been given.
X=-3
The Answer to this question is 9 (2B+4) and (1B+3)
