Step-by-step explanation:
you can follow the same procedure for others
Answer:−18x>36
Divide both sides by −18. Since −18 is negative, the inequality direction is changed.
x< −18
36
Divide 36 by −18 to get −2.
x<−2

Check the picture below.
notice, it simply got mirrored over the vertical y-axis.
Multiply the first equation by 2
2x + 2y =30
now we’ll add the second equation to the first equation
2x + 2y =30
-2x+5y= -2
7y=28
divide by 7
y=4
now plug y back into the first equation
x + 4 = 15
subtract 4
x=11
