Can someone me with these two questions on substitution.

Number 23:

x=7

y=6

Number 24:

x=-6

y= -5

Step-by-step explanation:

Number 23: You have to make one of the equations have only one variable per side

x-y=1 to x=1+y     Then you put the 1+y in all the x's spots on the other equation

2(1+y)=14           Distribute the 2 to 1+y

2+2y=14            Subtract 2 from both sides

2y=12                 divide both sides by 2

y=6                     Now you fill in your answer for six to find the x

x-y=1

x-6=1                   Add six to both sides

x=7

Number 24: You have to have one equation have only one variable per side

x+3y=-36    to    x=-36-3y    now you fill in all the spots with x's with -36-3y

x-4y=-1              fill in the x spot

-36-3y-4y=-1         simplify the -3y and the -4y to -7y

-36-7y=-1                Add 36 to both sides

-7y=35                  Divide by -7 so the y will be positive

y=-5                 Now fill in the y with -5 to one of the equations

x-4y=-1           fill in the y spot

x-(-5)=-1           a negative by a negative is a positive so make the 5 positive

x+5=-1                Subtract 5 from both sides

x=-6

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
