Answer:

x>4/5

Step-by-step explanation:

<em>Subtract by 5 from both sides of equation.</em>

<em>5-2x-5<8x-3-5</em>

<em>Simplify.</em>

<em>-2x<8x-8</em>

<em>Subtract by 8x from both sides of equation.</em>

<em>-2x-8x<8x-8-8x</em>

<em>Simplify.</em>

<em>-10x<-8</em>

<em>Multiply by -1 from both sides of equation.</em>

<em>(-10x)(-1)>(-8)(-1)</em>

<em>Simplify.</em>

<em>10x>8</em>

<em>Divide by 10 from both sides of equation.</em>

<em>10x/10>8/10</em>

<em>Simplify, to find the answer.</em>

<em>8/10=4/5</em>

<em>x>4/5 is the correct answer.</em>

Answer:

Isolating the x.

Step-by-step explanation:

The first step to solving this problem is to isolate the variable, x.

To do so, subtract 8x and 5 from both sides.

Step #1)

5 - 2x < 8x - 3

5 (-5) - 2x (-8x) < 8x (-8x) - 3 (-5)

-2x - 8x < -3 - 5

-10x < -8

PLZ HELP ASAP!!! I WILL NAME BRAINLIEST!! 65 POINTS!! (:

Answer:

1. 44 + 3x

2. 2y - 8

3. x - 6

15. $5\frac{7}{8}$

16. $6\frac{1}{3}$

17. $3\frac{7}{9}$

Step-by-step explanation:

1. 7² + 2² - 5 - 4 + 3x

49 + 4 - 5 - 4 + 3x

53 - 5 - 4 + 3x

48 - 4 + 3x

44 + 3x

2. - y - 5 + y + 2(2y-y) - 3

-y - 5 + y + 4y - 2y -3

-y - 5 + 5y - 2y - 3

4y - 2y - 5 - 3

2y - 8

3. 5x -3 - x - 3(x + 1²)

5x - 3 - x - 3x - 3

4x - 3x - 3 -3

x - 3 -3

x - 6

15. $7\frac{1}{4} - 1\frac{3}{8}$

= $7 \frac{2}{8} - 1\frac{3}{8}$

= $\frac{58}{8} - \frac{11}{8}$

= $\frac{47}{8}$ → $5\frac{7}{8}$

16. $9 - 2\frac{2}{3}$

= $\frac{54}{6} - 2\frac{4}{6}$

= $\frac{54}{6} - \frac{16}{6}$

= $\frac{38}{6}$ → $6\frac{2}{6}$ → $6\frac{1}{3}$

17. $10\frac{1}{3} - 6\frac{5}{9}$

= $10 \frac{3}{9} - 6\frac{5}{9}$

= $\frac{93}{9} - \frac{59}{9}$

= $\frac{34}{9}$ → $3\frac{7}{9}$

Hope this helps.
