(2\5)
5-
6x-5
(5 × 7) ÷ 5 = 7
Assuming you mean 5=2x-5, 10=2x, 5=x4x-15
If you mean: kk-5 then it can be k^2-5 But if you mean: k+k-5 then it can be 2k-5
5 plus 8
If you mean: x2+12x+35 then it is a quadratic expression that can be factored as: (x+5)(x+7)
It could mean the agebraic expression of: 5*(x-1) or 5x-5
If it doesn't have an equals sign or inequality relationship it is a relation. y=3 is an equality. 3x+5 is an expression.
Evaluating the expression is usually used in math, and it means solve the question.
This is ex. Of numerical expression 5-5, 5/5 5+5, 5*5
