Answer:
-4
Step-by-step explanation:
The given equations are as follows:
[tex]\[\frac{1}{2}x+\frac{1}{4}y=5\][/tex]
[tex]\[2x +\frac{3}{8}y=5\][/tex]
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
