The value of A in the expression is 18
The expression is given as:
[tex](7)8 - 6 \div 2 + (A)3 = 107.[/tex]
Evaluate the quotient
[tex](7)8 - 3 + (A)3 = 107.[/tex]
Open all brackets
[tex]56 - 3 +3A = 107.[/tex]
Subtract 3 from 56
[tex]53 +3A = 107.[/tex]
Subtract 53 from both sides
[tex]3A = 54[/tex]
Divide both sides by 3
[tex]A = 18[/tex]
Hence, the value of A in the expression is 18
