Answer:
A) is your answer
Step-by-step explanation:
Multiply the 2x by 9x
then you take the second variable in the second equation and mulitply it by 9x. giving you 98 x squared
THEN you take 9x times Negative 3 and get -87
AND NEGATIVE 5 TIMES NEGATIVE 3 IS
POSTIVE 15
12 + 5x > 2(8x - 6) - 7x
12 + 5x > 16x - 12 - 7x
5x - 16x + 7x > -12 - 12
-4x > -24 / : (-4)
x < 6
