X=2

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5

654326. Or 154326. or something else.

3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5

If a + b = 6, what is the value of 3a + 3b?

3b + 6 = 12 3b = 6 b = 2

b = -8

b = -6

12a + 6b + 6c = 6(2a + b + c)

3b + 2a = 2 and -2 + a = 8 -2 + a = 8 can be rearranged to show a = 8 + 2 = 10 (Effectively 2 has been added to both sides.) As a = 10, the value for a can now be substituted in the equation 3b + 2a = 2 3b + 2x10 = 2 : 3b + 20 = 2 this can be rearranged to show 3b = 2 - 20 = -18 and dividing both sides by 3 gives b = -6.

20 = 400

-6(a-3b-9c)

It is: 4b+6

20 + 6 - 56 = -30
