Question

Solve the two-step equation.

-0.45x + 0.33 = -0.66

What is the solution?
x = -2.2
x = -1.4
x = 1.4
x = 2.2

Answer 1

Answer:

$- - 0.66 - 0.33 = - 0.45$

$- 0.99 = 0.45x \: \: \: 0.99 \div 0.45 =x$

$2.2 = x$

Answer 2

Answer:

The correct answer is x=2.2.

Step-by-step explanation:

The above question is a simple linear equation. An algebraic equation is said to be linear if the variables in the equation are of the degree 1. It is of the form: $ax + b = 0$

where x is the variable, a and b are constants, and a is not equal to zero.

It is expected to form a straight line when graphed.

Given equation: $-0.45x + 0.33 = -0.66$

Changing sides of the variables,

⇒ $0.45x=0.33+0.66$

Adding the values on the right hand side,

⇒ $0.45x=0.99$

Dividing the values to get the value of x,

⇒ $x=0.99/0.45$

⇒ $x=2.2$
