Question

Solve the system of linear equations by substitution. x-2y=6 3x-5y=11

Answer 1

Answer:

x = -8, y = -7

Step-by-step explanation:

=> x = 6 + 2y

substitute x = 6 + 2y into the equation 3x - 5y = 11 to solve for y:

=> 3(6 + 2y) - 5y = 11

=> 18 + 6y -5y = 11

=> y = -7

substitute y = -7 into the equation x - 2y = 6 to solve for x:

=> x - 2(-7) = 6

=> x +14 = 6

=> x = -8
