X + 3 * 21 = 12
x + 63 = 12
x = 12-63

Alx+b) = 4x + 10

Leokris [45]

Answer:

a=4, b=5/2

Step-by-step explanation:

Assuming the given equation is

$a(x + b) = 4x + 10$

We expand the left hand side to get:

$ax + ab = 4x + 10$

If this equation must have infinitely many solutions, then

$ax = 4x \\ \implies \: a = 4$

Also we must have

$ab = 10$

Put a=4 to get:

$4b = 10$

$b = \frac{10}{4} = \frac{5}{2}$
