Tyson began solving the system 4x+2y=6 { 4x+5y=15 by writing -3y=-9. which property justifies this step? a. substitution property of equality b. multiplication property of equality c. subtraction property of equality d. division property of equality

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )
