8 - 3x - x = 12
8 - 2x = 12
-2x = 12 - 8
-2x = 4
x = -2
Answer:
Your answer for the above equation is D
2y+3x-5x^2-g contains 4 terms that cannot be further simplified without know the values for the variables y, x, and g. Although 3x and -5x^2 contain the same variable x, since they have have different exponents, we can not directly add them together without knowing the value of x.
The answer is 4.
X = 5
So 3x = 3(5) = 15
3x = 15
