The value of x is 7 when HJ = 7x - 27.
Built-in functions for subtracting, dividing, and multiplying can also be used to specify arithmetic operations. The arithmetic operator is the operator that executes the arithmetic operation.
Subtraction operation: Takes the right-hand operand and subtracts it from the left-hand operand.
For instance, 12 -2 = 10
Given that HJ = 7x minus 27,
To find the value of x.
IJ = x - 1 and HI = 3x - 5.
HJ = HI + IJ in this case.
Change the values of HI and IJ.
⇒ 7x - 27 = 3x - 5 + x - 1
Rearrange the corresponding terms and use the arithmetic operations.
⇒ 7x - 4x = 27 - 5 - 1
⇒ 3x = 21
⇒ x = 21/3
divided by three
⇒ x = 7
