Use a graphing tool to solve the system. 3x-8y=29 3x+y=-2 which ordered pair is the best estimate for the solution to the system? a (0.75, -2.25) b.(0, -3.75) c.(0.5,-3.5) d.(0,-2) i am so

C. ( 0. 5, -3. 5)

Step-by-step explanation:

3x - 8y = 29 (1)

3x + y = -2 (2)

subtract (2) from equation (1)

-9y = 31

Divide bothside by -9

-9y / -9 = 31/ -9

y = -3. 4

substituting y= -3. 4 in equation (2)

3x + y = -2

3x + (-3. 4) = -2

3x - 3. 4 = -2

add 3. 4 to bothside of the equation

3x - 3. 4 + 3. 4 = -2 + 3. 4

3x = 1. 4

Divide bothside by 3

3x / 3 = 1. 4 / 3

x = 0. 5

-2 is the right
