3x+12x = 15 15x = 15 x = 1
The answer is 180.
If you mean -12x+3y = 15 then y = 4x+5
Ill show you some examples: Ex. 1:3x + 4 - x + 16 + 12x(4 + 16) + 3x - x +12x20 + 2x + 12x20 + 14xEx. 2:15 - 12x + 4 - 2 + 6x(15+4-2) - 12x + 6x(19-2) - 12x + 6x17 - 18xTo solve these problems, first group like numbers. Then solve the problem until you can't solve anymore!
12x-17x = -5
3x+12x = 15 15x = 15 x = 1
The answer is 180.
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
If you mean -12x+3y = 15 then y = 4x+5
If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.
So the given line is y=12x-8 and the given point is x=2 y=15? 15=12*2+m m=-9 y=12x-9
36 - 21 + 15 = 30 36 - 21 - 15 = 0
12x+15p-6p+11x = 12x+11x+15p-6p = (12+11)x+(15-6)p = 23x + 9p
