Solve for x:<br> (2x/3) + 10 = (x/5) + (36/5)
Reil [10]

Answer:

x = -6

Step-by-step explanation:

(2x/3) + 10 = (x/5) + (36/5)

15*[(2x/3) + 10 = (x/5) + (36/5)]   <em>[Multiply both sides by 15 in order to convert the fractions to whole numbers]</em>

(15/3)*2x +15*10 = (15/5)x + (15/5)*36

5*2x + 150 = 3x + 3*36

10x +150 = 3x + 108

7x = -42

x = -6

===

<u>Check:</u>

Does (2x/3) + 10 = (x/5) + (36/5) work for x = -6?

(2(-6)/3) + 10 = (-6/5) + (36/5) ?

-4 + 10 = (30/5) ?

6 = 6  YES

Solve for x Enter the solutions from least to greatest . (x - 4)(- 5x + 1) = 0 lesser x = greater x =
Reil [10]

Answer:

lesser x = \frac{1}{5}

Greater x = 4

Step-by-step explanation:

Given expression is,

(x - 4)(-5x + 1) = 0

Either (x - 4) = 0

x = 4

Or (-5x + 1) = 0

5x = 1

x = \frac{1}{5}

Therefore,  lesser x = \frac{1}{5}

Greater x = 4
