HELP ME PLEASE SOMEONE How do i do the substitution method for this:
y=x-1
and
y=-x+5

Step-by-step explanation:

Think this way

Solve one equation for one of the variables.

Substitute (plug-in) this expression into the other equation and solve.

Resubstitute the value into the original equation to find the corresponding variable.

x = 3

y = 2

Step-by-step explanation:

Since both equations are equal to y, you can set them equal to each other.

So...

x - 1 = -x + 5

Combine like-terms and simplify. Isolate the x. Add the x to the left from the right and add the 1 to the right from the left. Then divide to completely isolate the x.

2x = 6

x = 3

Now we just plug 3 in place of x for either equation.

y = (3) - 1

y = 2

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !
