Answer:
[tex]\large \textsf{$c = \dfrac{d+ab}{a}$}\\\\[/tex]
Step-by-step explanation:
1. Distribute a:
a(c - b) = d
a(c) + a(-b) = d
ac - ab = d
2. Add 'ab' to both sides:
ac - ab + ab = d + ab
3. Divide both sides by 'a' to isolate 'c':
[tex]\large \textsf{$\dfrac{ac}{a} = \dfrac{d+ab}{a}$}\\\\\large \textsf{$c = \dfrac{d+ab}{a}$}\\\\[/tex]
Hope this helps!
