Answer:
(2, 1 )
Explanation:
given the system of equations
y = 6x - 11 → (1)
- 2x - 3y = - 7 → (2)
substitute y = 6x - 11 into (2)
- 2x - 3(6x - 11) = - 7 ( distribute parenthesis on left side and simplify )
- 2x - 18x + 33 = - 7
- 20x + 33 = - 7 ( subtract 33 from both sides )
- 20x = - 40 ( divide both sides by - 20 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (1)
y = 6(2) - 11 = 12 - 11 = 1
solution is (2, 1 )
