If x=7 and y=-11, 5x+y = 5(7) -11 = 35-11 = 24.
If x=7 and y=11, 5x+y = 5(7) +11 = 35+11 = 46.
Let the number be x and so the expression is: 5x-11
The expression is: 6-5x when simplified
5x-7 is an algebraic expression
Well, isn't that just a happy little math problem! When x is multiplied by 8, we get 8x. So, if we want to find the value of 5x, we simply multiply 5 by the value of 8x. That gives us 40x. Just remember, there are no mistakes in math, only happy accidents!
5x - 11 - 36 is a math equation. 5x - 11 -36 can be simplified to read 5x- 47. I suspect that there is an equals missing, ie the question was/should be: "Solve for x in 5x - 11 equals -36" 5x - 11 = -36 → 5x = -25 → x = -5
