Equations are expressions that are related by the equality sign.
The value of B is 9
How to determine the value of B
The equation is given as:
[tex]8x+ By= 60[/tex]
The equation goes through point (3,4).
So, the equation becomes
[tex]8 * 3+ 4 * B= 60[/tex]
Evaluate the products
[tex]24+ 4B= 60[/tex]
Subtract 24 from both sides
[tex]4B= 36[/tex]
Divide both sides by 4
[tex]B= 9[/tex]
Hence, the value of B is 9
