Respuesta :
(17-5)(x+6)-(3x-12)=0
12(x+6)-(3x-12)=0
12x-(3x-12)+72=0
12x-3x+12+72=0
9x+84=0
9x=-84
x=9+1/3
The solution of the expression is x = -9.33.
What is an expression?
Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given the expression for x as:
(17 – 5)(x + 6) = 3x – 12
(17-5)(x+6) - (3x-12)=0
12(x+6) - (3x-12)=0
12x - (3x-12) + 72=0
Rearrange the likewise terms and apply the arithmetic operations
12x - 3x + 12 + 72=0
9x + 84 = 0
9x = -84
Divided by 9
x = -9.33
Hence, the solution of the expression is x = -9.33.
