Explanation: Algebraic expression is a mathematical expression that consists of variables, numbers, and operations.
J: ← Variable (letter/symbol)
Product: ← means to multiply by the numbers, fractions, multiples, and factors.
7j=91
You can also divide by 7 both sides of an equation.
[tex]\frac{7j}{7}= \frac{91}{7}[/tex]
Finally, simplify by equation.
[tex]\frac{91}{7}=13[/tex]
[tex]13*7=91[/tex]
[tex]7*13=91[/tex]
[tex]91/13=7[/tex]
Final answer: [tex]\boxed{j=13}[/tex]
Hope this helps!
Thanks!
Have a great day!
