Answer :

subtract .3x from 2.1x and you get 1.8x
add 4.4 to 5.14 and you get 9.54
divide 9.54 by 1.8
x = 5.3

The value of x = 5.3.

What is an Equation?

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equation is,

0.3x +5.14 = 2.1x -4.4

The equation here formed is made of two expressions,

Expression 1:  0.3x +5.14 and,

Expression 2 : 2.1x -4.4

In the expressions, the variable is x, and the constants are 0.3, 5.14, 2.1, -4.4

Solving for x,

0.3x +5.14 = 2.1x -4.4

Taking variable on the left side, and the constants on the right side.

Taking the like terms on one side,

0.3x - 2.1x = -4.4 -5.14

The negative sign gets cancelled,

-1.8x = -9.54

Dividing 1.8 on both sides.

x = (-9.54 / -1.8)

x = 5.3

The value of x is 5.3.
