Answer:
The value of x is 7 when HJ = 7x - 27.
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.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
Given that HJ = 7x - 27
To determine the value of x.
HI = 3x - 5 and IJ = x - 1
Here HJ = HI + IJ
Substitute the values of HI and IJ,
⇒ 7x - 27 = 3x - 5 + x - 1
Rearrange the likewise terms and apply the arithmetic operations
⇒ 7x - 4x = 27 - 5 - 1
⇒ 3x = 21
⇒ x = 21/3
Divided by 3
⇒ x = 7
