Answer:
a= G/c
Step-by-step explanation:
To solve one expression for certain variable, it means to express the expression in term of the said variable.
In this case we have G = ca and we need to solve this expression for a, meaning we have to express it in terms of a.
To do this we need to leave the a by itself in one side of the expression.
Let's proceed: [tex]G = ca\\\frac{G}{c} = a[/tex]
Notice that we divided by c in order to leave the a by itself,
Therefore solving for a we get:
a = G/c
