Question

y = x - 2
y = 4x + 1

Solving systems by substitution .

Answer 1

just put the value of y from the first equation in second:
x-2=4x+1
solve it for x
put value of x in any original equation - you will have y.
Let me know if there is any questions

Answer 2

how do i solve for x ?

Answer 3

x-2=4x+1
put all x on one side:
4x-x+1=-2
-1 from both sides:
3x=-3
divide both sides by (3):
x=-1
now, you put value of x say in first equation:
y=x-2=-1-2=-3
so, y=-3
your answer should be:
x=-1, y=-3

Answer 4

thank you so much !
