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

from first equation we have y, since:
\[\Large y = 4x - 3\]

Answer 2

now I replace y with 4x-3 into the second equation, so I get:
\[\Large 2x + 7\left( {4x - 3} \right) = 41\]
