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
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.
