-4x/7 > 10

Multiply both sides by 7:

-4x > 70

Divide both sides by -4"

x > 70 / -4

Simplify the fraction:

70/-4 = 35 / -2

Because the fraction is negative you need to reverse the inequality sign:

x < -35/2

The answer is the first one: {x|x < -35/2}

2(1 − x) = 9(1 + 2x) + 52(1 − x) = 9(1 + 2x) + 5

marusya05 [52]

Solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$

Step-by-step explanation:

We need to solve the equation $2(1-x) = 9(1 + 2x) + 5$ and find value of x

Solving:

$2(1-x) = 9(1 + 2x) + 5\\2-2x=9+18x+5\\Adding\,\,-18x\,\,on\,\,both\,\,sides:\\2-2x-18x=9+5\\Adding\,\,-2\,\,on\,\,both\,\,sides\\-20x=14-2\\-20x=12\\x=\frac{12}{-20}\\x=-\frac{3}{5}$

So, solving the equation $2(1-x) = 9(1 + 2x) + 5$ we get $x=-\frac{3}{5}$
