The expression -3X - 4 represents a linear equation in one variable, where X is the variable. This expression can be simplified by combining like terms. In this case, there are no like terms to combine, so the expression remains as -3X - 4. This expression can also be interpreted as a linear function with a slope of -3 and a y-intercept of -4.
Well, honey, -3X - 4 is just an algebraic expression that simplifies to -3X - 4. It's like a bad haircut - not the end of the world, but you might want to fix it. Just remember, math won't solve all your problems, but it's a good start.
Oh, dude, you're hitting me with some math now! So, like, -3X - 4 is just a fancy way of saying "negative 3 times X minus 4." It's like when you owe your friend 3 bucks and then you find 4 more dollars in your pocket - you're still in debt, man!
Not sure of what you're asking, but if you mean 3 times 4, then that is 12. If it is 3x(4), then it is 12x.
3x - y = -4 3x - y = 0 Those lines do not intersect. They are parallel. You can demonstrate by solving either of them for one of the two variables, then plugging it's value into the other: 3x - y = -4 ∴y = 3x + 4 Now substitute: 3x - y = 0 ∴ 3x - (3x + 4) = 0 ∴ 3x - 3x - 4 = 0 ∴ -4 = 0 This result is obviously incorrect, indicating that the lines do not intersect.

-(3x-4) = -3x + 4
y=3x+4 -3x+y=4 x=-1/3
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
