Question

Solve the following system using substitution. Write the solution as an ordered pair.

2x + y = 5
8x – y = 45

Answer 1

hi there @ami2

to solve with substitution, you'll need to set one equation equal to y

for example:
2x+y=5
-2x -2x
y= -2x+5

making sense so far?

Answer 2

@Ami22

now that we have set the value of y as equal to -2x+5, we can substitute it in to the other equation

8x-y=45

8x-(-2x+5)=45

Answer 3

thank you

Answer 4

Jamierox4ev3r can you answer this for me please

6x - 2y = 50
x + 3/2y = 12
