Question

1. Y=4x+24 and y=^x+6

What the x value is a solution to equation

2 . 4x+5y=7
y=3x+9
^ Solve the system using Substitution show all work

9x+5y=35
2x+5y=0
^ Solve the system using linear Combination Show all work

Answer 1

#1. try substitution. Since y=x+6,
x+6 = 4x+24
x = -6
and y = x+6 = 0

#2. substitution will work here too, since y=3x+9
4x+5(3x+9) = 7
x = -2
and y = 3

#3. use elimination. If you subtract the bottom equation from the top one, you get
7x = 35
x = 5
and y = -2

If these still bother you, you need to review the topic some more, either in your text, or online, where youi will find many examples and videos.
x =
