Solving Systems of Linear Equations - Item 9500
Question 2 of 7
Which choice is the most efficient first step to solve this set of equations?
Reference
y = 2x + 4
3x + 4y = 17
CLEAR
CHE
Language
y + 3x + 4y = 2x + 4 + 17
Add the two equations together
3x + 4(2x + 4) = 17
Substitute (2x + 4) for y
in the second equation
ENUE
3x + 4y - y = 17 - (2x + 4)
Subtract the first equation
from the second equation
y-(3x + 4y) = 2x + 4 - 17
Subtract the second equation
from the first equation
