Hey there! :D
Plug in the solution.
5(2) + 2(-3)=4 || 10-6=4 || 4=4 <== true
4(2) + -3= 11 || 8-3= 11 || 5=11 <== not true
4. is not a solution.
3(1)+2(5)=13 || 3+10=13 || 13=13 <== true
4(1)-3(5)=-11 || 4-15=-11 || -11=-11 <== true
5. is a solution
2(-6) - 5(-2)=-22 || -12+10=-22 -2=-22 <=== not true
6. is not a solution
I hope this helps!
