2x-y²=

for x=5 & y=3

1. In order to solve this problem place five to take place of x and three to take place of y.

2(5)-3²=

2. Next step is to multiply three times three because of the order of operation rule, states that since there are not parentheses, exponents should be done first.

2(5)-(3*3)=

2(5)-9=

3. Than you multiply two times five because multiplication

is the next step in order of operation.

2(5)-9=

10-9=

4. Last step is to solve by subtracting nine from ten. The

answer is one.

10-9=1
