Answer:
Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:
combine the equations:
divide both sides by -48:
substitute the value of y to the second equation
simplify multiplication:
cancel 12 from both sides:
divide both sides by 4
therefore our solution is
Remove both sets of brackets.
18 - 9x - 8 + 12x > 9 Collect like terms on the left.
12x - 9x + 18 - 8 > 9
3x + 10 > 9 Subtract 10 from both sides.
3x > 9 - 10
3x > - 1 divide by 3
x > -1/3
Notice what the graph is telling you. A blue dotted line is going through x = - 1/3 or - 0.3333
Everything to the right of - 0.333 is colored blue and that means anything to the right if going to be a solution to the inequality. To confirm this for yourself, try zero and 1. Both should give larger than 9 solutions.
