## anonymous one year ago 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)

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

2. Michele_Laino

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