Answer:
a=9
Step-by-step explanation:
In 7a-19=44, you want to find what a equals to, so in order to find that, you can isolate 7a in the equation.
7a-19+19=44+19
If you add 19 to both sides, the new equation is
7a=63
Now you have to isolate the variable a, and in order to do that, divide both sides by 7.
7a/7=63/7
Which leaves you with,
a=9
