How do you solve -3 (x - 1) + 8 (x - 3) = 6x + 7 - 5x

x = 7

Step-by-step explanation:

-3(x - 1) + 8(x - 3) = 6x + 7 - 5x

multiply in "-3" and "8"

-3x + 3 + 8x - 24 = 6x + 7 - 5x

move the unknowns to the left and constants to the right

-3x + 8x - 6x + 5x = 7 - 3 + 24

4x = 28

divide both sides by 4

x = 7

answer: i believe its b. if you sound out the sentences that sounds wrong.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
