Simplify \frac{5}{3}x35x to \frac{5x}{3}35x
x-\frac{5x}{3}<3x−35x<3
2
Simplify x-\frac{5x}{3}x−35x to -\frac{2x}{3}−32x
-\frac{2x}{3}<3−32x<3
3
Multiply both sides by 33
-2x<3\times 3−2x<3×3
4
Simplify 3\times 33×3 to 99
-2x<9−2x<9
5
Divide both sides by -2−2
x>-\frac{9}{2}x>−29

Answer:
1/27
Step-by-step explanation:
1/3 / 1/9 = 1/27
Answer:
x= -20, y= 10
Step-by-step explanation:
Label the two equations:
-7x -10y= 40 -----(1)
x= -2y -----(2)
Substitute (2) into (1):
-7(-2y) -10y= 40
Expand:
14y -10y= 40
Simplify:
4y= 40
Divide both sides by 4:
y= 40 ÷4
y= 10
Substitute y= 10 into (2):
x= -2y
x= -2(10)
x= -20
