4x-y
x= 5
y= 6
replace in the ecuation above:
4•5-6= 20-6= 14
6 consecutive even numbers
First x
Second x+2
Third x+4
Fourth x+6
Fifth x+8
Sixth x+10
126=x+x+2+x+4+x+6+x+8+x+10
126=6x+30
Subtract 30 from both sides
96=6x
Divide both sides by 6
x=16
Fourth x+6=16+6=22
Isolate the variable by dividing each side by factors that dont contain the variable x=9
