-3x -4=2
add four to both sides
-3x=6
divide by (-)3 on both sides
x= -2
to check:
-2(-3) -4=2
6-4=2
It checks.

What is 3 x 4 x 7 x 2 equals?
Just multiply across: 3x4=12 12x7=84 84x2=168
Why is that 3x4 is not equals to 13?
Because 3 x 4 = 12
What is the answer for x2 plus 1 plus 3x4 equals 2?
-7.5?
If x equals 4 and y equals 8 then 3x plus 8y equals?
8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
What is 3x4 plus 5x3 plus x2 - 5 divided by x 2?
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
Will 6x2 equals 3x4 will that be commutative property of multiplication?
No. 6 x 2 = 2 x 6 is.
What is 3 x 4 x 7 x 2 equals?
Just multiply across: 3x4=12 12x7=84 84x2=168

8x8 = 64 so it is 64 (the y) 3x4 = 12 so it is 12 (the x) 64+12 is 76.
What is 3x4 plus 5x3 plus x2 - 5 divided by x 2?
3x4 plus 5x3 plus x2 - 5 divided by x 2 =[(3x4) + (5x3) + (x2 - 5)]/x2 =(12 + 15 + x2 -5)/x2 =(27 - 5 + x2)/x2 =(22 + x2)/x2
What is the answer to 3x4 7x3 4x2 equals 0?
The four solution values of x of 3x4 + 7x3 + 4x2 = 0 are: x = -11/3, -1, 0 (repeated) 3x4 + 7x3 + 4x2 = 0 ⇒ x2(3x2 + 7x + 4) = 0 ⇒ x2(3x + 4)(x + 1) = 0 ⇒ x2 = 0 → x = 0 (repeated) or (3x + 4) = 0 → x = -4/3 = -11/3 or (x + 1) = 0 → x = -1
What is 3 x 4 to the power of 2?
3x4=12 12 to the power of two = 144
