Given the system of equations. Which of the {-5x+y=6 --> y=5x+6 3x-y=14}
options represents the resulting equation after an equivalent expression for y is substituted into the second equation. 3x - (5x + 6) = 14 -3x + 5x + 6 = 6 3(5x + 6) - y = 14 -3x(5x + 6) + y = 6
The first thing we must do is solve the problem step by step to choose the correct option. Step 1: Clear y from the first equation: -5x + y = 6 y = 5x + 6 Step 2: Replace this value of y in the second equation: 3x-y = 14 Substituting: 3x- (5x + 6) = 14 answer the resulting equation after an equivalent expression for y is substituted into the second equation is 3x- (5x + 6) = 14
