1.y=x+2 2.y=4x-1 its for My math notes and i dont know how to do this!!

x

−

2

=

4

x

+

1

4

x

−

x

=

−

2

−

1

3

x

=

−

3

x

=

−

1

With a value for

x

you can substitute in one of the two equations and obtain

y

. Because both equations has to be valid at the same time, both equations must give you the same number for

y

. Let's try:

y

=

x

−

2

y

=

−

1

−

2

y

=

−

3

and, with the second equation

y

=

4

x

+

1

y

=

4

(

−

1

)

+

1

y

=

−

4

+

1

y

=

−

3

.

It works! Then our solution is given by

x

=

−

1

and

y

=

−

3

.

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation. Point Form: ( 5 2 , 9 2 ) Equation Form: x = 5 2 , y = 9 2

I might be wrong so sorry abt dat
