Answer :
To solve this first we need to get are chunk which is already solved for here as
Y=(4x) so one the chunk side of this we dont have to solve for it, so now we can just skip right to solving this equation like so. First input the numbers x+(4x)=5,
Distribute/Combine like terms in this case
5x=5
Divide by 5
x=1
So now that we have x we can plug it into are chunk and then we have are answer
Y=(4x)
Y=(4*1)
Y=4
So are end answers are [tex] \left \{ {{y=4} \atop {x=1}} \right. [/tex]

{ y = 4x
{ x + y = 5
y = 4x ----> Substitute y for 4x in the 2nd equation:
x + y = 5
x + 4x = 5
5x = 5
x = 5
5
x = 1
x = 1 -----> Substitute x for 1:
y = 4x
y = 4 . 1
y = 4
S = { 1 , 4 }
{ x + y = 5
y = 4x ----> Substitute y for 4x in the 2nd equation:
x + y = 5
x + 4x = 5
5x = 5
x = 5
5
x = 1
x = 1 -----> Substitute x for 1:
y = 4x
y = 4 . 1
y = 4
S = { 1 , 4 }
