Answer:
D. (2, 1)
Explanation:
Given:
y = 6x - 11
-2x - 3y = -7
Required:
Find the solution.
Solution:
y = 6x - 11 ---› eqn. 1
-2x - 3y = -7 ----› eqn 2
Substitute y = (6x - 11) into equation 2.
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-20x + 33 = -7
Subtract 33 from each side
-20x = -7 - 33
-20x = -40
Divide both sides by -20
x = -40/-20
x = 2
Substitute x = 2 into equation 1.
y = 6x - 11 ---› eqn. 1
y = 6(2) - 11
y = 12 - 11
y = 1
The solution is very (2, 1)
