Answer:
-4
Step-by-step explanation:
The given equations are as follows:
The coefficient of x in the second equation is 2.
So in order to eliminate x we need to multiply the first equation by a value so that the coefficient of x becomes -2.
Since the coefficient of x in the first equation is \[\frac{3}{8}\], it needs to be multiplied by -4.
So the required multiplier for the first equation is -4
