The product of 5 and twice a number

The product of 5 and twice a number is 10X

Solving linear equation mean calculating the unknown variable from the equation.

Let the linear equation : y = mx + c

If we draw the above equation on Cartesian Coordinates , it will be a straight line with :

m → gradient of the line

( 0 , c ) → y - intercept

Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :

If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :

Let us tackle the problem.

This question is about making algebraic expressions.

Let :

The number = X

If the number is doubled , then it becomes 2X.

The product of 5 and this number can be written as :
