The value of the unknown variable "x" given that -6x + 3= 45 is -7
Equations are expressions separated by an equal sign. They can contain one or more variables.
The equation given in question is a linear equation containing one unknown variable "x".
The equation is expressed as -6x + 3 = 45
To get the value of x, we will follow the steps below:
Step 1: Subtract 3 from both sides of the equation
-6x + 3 - 3 = 45 - 3
-6x = 42
Step 2: Divide both sides of the expression by -6
-6x/-6 =42/-6
x = -7
This shows that the value of the unknown variable "x" is -7.

the dog the chicken and the chicken ate the dog
(−7a − 19c) − (−12a + 30c) − (−21a − 11c)
= −7a − 19c + 12a - 30c + 21a + 11c
= (-7a + 12a + 21a) + (11c - 19c - 30c)
= 26a - 38c
= 2(13a - 19c)
