3X + 6 = 21
subtract 6 from each side
3X = 15
divide both sides integers by 3
X = 5

What is 3x plus 2 equals 3x plus 6?
3x + 2 = 3x + 6 This is not possible.
4x plus 6 equals 21 plus 3x?
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15
What is the difference between y equals 3x plus 5 and 6 equals 3x plus 5?
what is a slope
How do you solve 3x minus 6 equals 21?
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
7x plus 4 equals 3x plus 16 equals?
x=6
What is 3x plus 2 equals 3x plus 6?
3x + 2 = 3x + 6 This is not possible.
4x plus 6 equals 21 plus 3x?
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15
What is the answer to 3x plus 6 equals 27?
3x + 6 = 27.Subtract 6 from both sides: 3x = 27 - 6 = 21.Divide both sides by 3: x = 21/3 = 7.x = 7
The order pair for 3x plus 5y equals 21 and -9x plus 4y equals -6?
x = 2, y = 3
What is answer 3x-6 equals 15?
3x-6=21-6=15
How can you write this 3x plus y equals 6?
3x+y=6
What is 3x-3 equals 7x 21?
If: 3x-3 = 7x+21 Then: x = -6
What is the difference between y equals 3x plus 5 and 6 equals 3x plus 5?
what is a slope
How do you solve 3x minus 6 equals 21?
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
7x plus 4 equals 3x plus 16 equals?
x=6
What is answer to 5x-4 equals 3x plus 6 equals?
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
