Question

)A system of equations is given below:

y = 4x − 3
2x + 7y = 41

Which of the following steps could be used to solve by substitution?

2(y = 4x − 3) + 7y = 41
4x − 3 = 2x + 7y
2x + 7(4x − 3) = 41
2(y = 4x − 3)

Answer 1

Well it tells you what Y equals so plug the Y value into the 2nd equation what do you get?

Answer 2

idk D: @kidrah69

Answer 3

plug it in
\[2x + 7(y~value~goes~here) = 41 \]

Answer 4

2x + 7(4x-3)? @kidrah69

Answer 5

yep :) good job!

Answer 6

so d? @kidrah69

Answer 7

i mean c @kidrah69

Answer 8
