Question

Hey, can someone explain an equation to me step by step? Ill fan and give a Medal.
I have to solve this using substitution, and I'm having a bit of difficulty.
y = 9x + 14
29x +7y = 6
I know the answer is ( -1, 5) Im just having difficulty understanding how you get that answer

Answer 1

since they gave you y= ... start by plugging that in for y in the equation below that

Answer 2

\[29 x +7 (9x+14)=6\]

Answer 3

oops

Answer 4

Wouldn't is be 7*14?

Answer 5

\[29x + 63x + 98= 6\]

Answer 6

sorry, got mixed up for a sec

Answer 7

Its fine :) so you add 29 and 63 equaling 92x

Answer 8

\[92x= 6-98\]

Answer 9

yes

Answer 10

\[x= -92/92 = -1\]

Answer 11

Then plug in x and solve for y right? Thanks for the help!

Answer 12

now that you have solved for "x". plug that same value in for x to get y

Answer 13

Sorry, Im having technical difficulties so Im replying slowly.

Answer 14

\[y= 9(-1) +14 = 14-9 = 5\]
