Solve the system of equations. 8x – 3y = 1 –2x + 3y = 11 a. (–1, –3) b. (–1, 3) c. (2, 5) d. (5, 2)

C. (2, 5)

Step-by-step explanation:

Looking at the answer choices, you can see that solving for y will tell you which choice is correct. We can eliminate x from the equations by adding 4 times the second equation to the first:

(8x -3y) +4(-2x +3y) = (1) +4(11) . . . . . adding the equations to eliminate x

9y = 45 . . . simplified; next we divide by 9

y = 5 . . . . . matches choice C

Check

8(2) -3(5) = 16 -15 = 1

-2(2) +3(5) = -4 +15 = 11 . . . . the answer checks OK in both equations

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

0,0
