Question

If 5a+b=14 then a = what explain how you got it pls

Answer 1

Answer:

$a = \frac{14 - b}{5}$

Step-by-step explanation:

The rule to know and follow is:

You can add, subtract, multiply or divide by anything so long as the same thing is done to both sides of the equals sign;

5a + b = 14

If we want to get: "a = ...", then we use the rule to isolate the variable a on one side of the equation;

Firstly, we subtract b from both sides:

5a + b - b = 14 - b

5a = 14 - b

Then, divide both sides by 5:

$\frac{5a}{5} = \frac{14 - b}{5} \\\\ a = \frac{14 - b}{5}$
