Question

Solve for a.
ab +c=d
a=b+c/d
O a = b/(C-d)
O a = (d - c)/b

Answer 1

Explanation:

ab +c=d

SUBTRACT c FROM BOTH SIDES.

ab + c (-c) = d - c

ab + 0 = d - c

ab = d-c

Divide both sides by b.

ab/b = (d-c)/b

a = (d-c)/b (FIRST EQUATION)

a=b+c/d

THIS IS ALREADY SOLVED FOR a. (SECOND EQUATION)

O a = b/(C-d)

O a = (d - c)/b

Answer 2

Value : c = ad - b

Explanation:

Given the equation: Solve for c;

Multiply both sides by d in we get;

subtract b from both sides we have;

Simplify:

ad - b = c

Therefore, the value of c is, ad -b
