3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
2x+3x = 5x
If: 3x = 15 Then: x = 5
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
3x+7=37 -7 -7 3x=30 /3 /3 x=10
3x-15x-y= 45 -12x-y=45 -y=12x+45 y=-12x-45 Solution set: straight line, y-intercept=-45 and slope =-12
3x+27=12x-45 Bring x to one side and the numbers to the other 45+27=12x-3x 72=9x x=8 For any step you don't understand message me
3x + 15 = 603x = 60 - 153x = 45x = 45/3Therefore, x = 15.
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
The answer to 3 times 3x-6-3 time 1+4x equals -45. This is a math problem.
3x+12 = 18 3x = 18-12 3x = 6 x = 2
Let the number be x: 3x-9 = 45 3x = 45+9 3x = 54 x = 18
3x-15 = -12
no
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!
3x-3x equal = 0
3x - 5y = 45At the y-intercept, x = 0.-5y = 45y = -9At the x-intercept, y = 0.3x = 45x = 15
