(6 * y) +9
Let the original number be y Therefore the new number is given by the expression 2y + 6
y-6
y = 4x + 6
Oh, dude, it's like this - when you divide 6 by a number in algebra, you just write it as 6 divided by x, where x is the mysterious number you're dividing by. So, the algebraic expression for 6 divided by a number is 6/x. Easy peasy, right?
(6 * y) +9
Let the original number be y Therefore the new number is given by the expression 2y + 6
X = 4(6-y)
Let the required answer be represented by 'y' and the variable number by 'n'. Then y = 4n + 3
13y-6
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
y-6
y = 4x + 6
y = 6 * ( x + 11)
Oh, dude, it's like this - when you divide 6 by a number in algebra, you just write it as 6 divided by x, where x is the mysterious number you're dividing by. So, the algebraic expression for 6 divided by a number is 6/x. Easy peasy, right?
y - 5x
y = -91k ( or -y = 91k)
