Answer:

4  assignments of math

Step-by-step explanation:

Gerald can complete a math assignment in 2 hours

Gerald can complete a physics  assignment in 1 hours

Equation : 2x+y=8

where x is the number of completed math assignments

y is the number of completed science assignments.

Since we are given that he decided to leave science assignment for the next day .

So, substitute y = 0

\Rightarrow 2x+0=8

\Rightarrow x=\frac{8}{2}

\Rightarrow x=4

Hence he can complete 4 assignments of math if he decides to leave the science assignments for the next day.
