1. y=x+4

y+3x

2. y=3x-10
y= 2x-5

3.x=-2y+!
x=y-5

4.y=5x+5
y=15x-1

5.y=x-3
y=-3x+25

6.y=x-7
2x+y=8

for #'s 2-5, set them equal to each other, so for #2:

2x-5=3x-10, then simplify

for #6, subtract 2x from the second equation, so it's y=2x+8, then set it equal to y=x-7

for #1, is it supposed to be y=3x?

y=5x+5

y=15x-5

y=3x-10

y=2x-5

To find the values of x and y for each given pair of equations, we can use a method called substitution or elimination. Here's how you can solve each pair of equations:

1. y = x + 4 (equation 1)
y + 3x (equation 2)

Since equation 2 doesn't have an explicit value for y, we can substitute the value of y from equation 1 into equation 2:

y = x + 4 (equation 1)
x + 4 + 3x (equation 2)

Now we have a single equation with only one variable:

4x + 4 = 0

Solving this equation, we find that x = -1. Substituting this value back into equation 1, we can find the value of y:

y = -1 + 4 = 3

So the solution for this pair of equations is x = -1 and y = 3.

You can apply a similar approach to solve the other pairs of equations. Substitution or elimination methods can be used depending on the complexity of the equations.
