Substitution Method Problems! PLZ HELP!!!

I'll give you some hints

1. y = 4x - 10

    y = 5 - x           set the y's equal

 4x - 10  = 5 - x        can you take it from here???

3.   y = 9 - 2x

    3y - 2x = 11      put the first equation into the second for y

3[ 9 - 2x]  = 11

27 - 6x  = 11        now....it should be easy......

Try  2  for yourself....it is similar to 3

1)

Step 1: Set the two equations equal to each other through substitution

4x-10=5-x

Step 2: Separate the variables on one side and the constants on the other

5x=15

Step 3: Divide both sides by 5 to get the x value

x=3

Step 4: Substitute x back into any equation of your choosing

I chose 5-x=y

5-(3)=y

y=2

Now go and do the other problems you lazy slacker

Also check with your teacher & ask your parents
