He is at 4 yards.

Step-by-step explanation:

Starts with 0.

Then loses 3 yard.

They are now at -3 yards

Then gains 7 yards.

They are now at 4 yards.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
