Explain how solving -7y > 161 is different from solving 7y > -161. Please and thank you :D

-7y > 161......here, u would divide both sides by -7...keep in mind, when dividing/multiplying by a negative number, the inequality sign changes.
y < 161/-7
y < -23

7y > -161...here u divide by 7
y > -161/7
y > -23

What is the value of x

goblinko [34]

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

$\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\$

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3
