Solve inequality for x -4(2x+4)>8x+64
Mkey [24]

Answer:

x< - \frac{16}{3}

Step-by-step explanation:

x 8x_16>8x+64

Add similar elemants:x - 8x= -7x

-7x - 16 > 8x + 64

Add 16 to both sides

-7x- 16 + 16 > 8x + 64 + 16

Simplify

- 7x > 8x + 80

Subtract 8x from both sides

-7x - 8x > 8x + 80 - 8x

Simplify

-15x > 80

Multiply both sides by - 1 ( reverse the inequality)

(-15x) ( - 1) < 80 ( - 1 )

simplify

\frac{15x}{15} < \frac{-80}{15}
