3x+4=10 To solve: 3x+4=10 3x=6 x=2
3x+12 = 18 3x = 18-12 3x = 6 x = 2
3x - 6 = 15 3x - 6 + 6 = 15 + 6 (NOTE: In an equation with =, you can do ANYTHING you want to the problem as long as you do the exact same thing to both sides.) 3x = 21 x = 7
It is a simultaneous equation and its solution is x = -1 and y = -5
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
The answer to the problem of 7-3x equals 34 is x equals -9.
3x+4=10 To solve: 3x+4=10 3x=6 x=2
The solution to this problem is x=5.
y=-3X the line would cross the y-axis at (0,0)
Add 10 to each side: 3x = 34 so x = Eleven-and-one-third
The equation 3X take away 11 times 2 equals -2. This is algebra math problem.
The equation 3X take away 11 times 2 equals -2. This is algebra math problem.
Here's the work for that problem. -3x+ 8.1= -18.9 -3x=-18.9-8.1 (subtracting 8.1 from both sides, or, moving it to the other side) -3x=-27 x=27
3x+12 = 18 3x = 18-12 3x = 6 x = 2
The answer to 3 times 3x-6-3 time 1+4x equals -45. This is a math problem.
1/2x+6=1/3x 3x+36=2x 3x=2x-36 x=-36
3x - 6 = 15 3x - 6 + 6 = 15 + 6 (NOTE: In an equation with =, you can do ANYTHING you want to the problem as long as you do the exact same thing to both sides.) 3x = 21 x = 7
