It can be: 7-4x as an algebraic expression
4x
X = " a number " X + 20
Write the general algebraic expression for each using matchstick?
x+7=y
18 - 3n
It can be: 7-4x as an algebraic expression
the + of a number and 10 k decreased by 4 = k-4
Let x be the number and so it is: 3x-18
(x - 25)*4
15 - 2x
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
4x
1/11
N/8
N/9
It is n + 14.
