Answer:
3a-b=14x-7ax
Step-by-step explanation:
Two equivalent expressions are shown in the equation :
a(7x + 3) = b + 14x
Let it assumed to form an equation in terms of a and b.
Opening brackets of both sides,
7ax+3a=b+14x
Taking constant terms to LHS and variables to RHS
3a-b=14x-7ax
Hence, the equation is "3a-b=14x-7ax".
