Answer:

-8/7

Step-by-step explanation:

By cross multiplication

=> 10(2x + 1) = 9(3x + 2)

=> 20x + 10 = 27x + 18

=> 27x - 20x = 10 - 18

=> 7x = - 8

=> x = - 8/7

Answer:

Multiply all terms by the same value to eliminate fraction denominators

2+13+2=910

\frac{2x+1}{3x+2}=\frac{9}{10}

(3+2)⋅2+13+2=(3+2)⋅910

(3x+2) \cdot \frac{2x+1}{3x+2}=(3x+2) \cdot \frac{9}{10}

2

Cancel multiplied terms that are in the denominator

(3+2)⋅2+13+2=(3+2)⋅910

(3x+2) \cdot \frac{2x+1}{3x+2}=(3x+2) \cdot \frac{9}{10}

2+1=(3+2)⋅910

2x+1=(3x+2) \cdot \frac{9}{10}

3

Re-order terms so that constants are on the left

2+1=(3+2)⋅910

2x+1=(3x+2) \cdot {\color{#c92786}{\frac{9}{10}}}

2+1=910(3+2)

2x+1={\color{#c92786}{\frac{9}{10}}}(3x+2)

4

Combine multiplied terms into a single fraction

2+1=910(3+2)

2x+1=\frac{9}{10}(3x+2)

2+1=9(3+2)10

2x+1=\frac{9(3x+2)}{10}

5

Distribute

2+1=9(3+2)10

2x+1=\frac{{\color{#c92786}{9(3x+2)}}}{10}

2+1=27+1810

2x+1=\frac{{\color{#c92786}{27x+18}}}{10}

6

Subtract 

1

1

 from both sides of the equation

2+1=27+1810

2x+1=\frac{27x+18}{10}

2+1−1=27+1810−1

2x+1{\color{#c92786}{-1}}=\frac{27x+18}{10}{\color{#c92786}{-1}}

8

Multiply all terms by the same value to eliminate fraction denominators

2=27+810

2x=\frac{27x+8}{10}

10⋅2=10⋅27+810

10 \cdot 2x=10 \cdot \frac{27x+8}{10}

9

Cancel multiplied terms that are in the denominator

10⋅2=10⋅27+810

10 \cdot 2x=10 \cdot \frac{27x+8}{10}

10⋅2=27+8

10 \cdot 2x=27x+8

10

Multiply the numbers

10⋅2=27+8

{\color{#c92786}{10}} \cdot {\color{#c92786}{2}}x=27x+8

20=27+8

{\color{#c92786}{20}}x=27x+8

11

Subtract 

27

27x

 from both sides of the equation

20=27+8

20x=27x+8

20−27=27+8−27

20x{\color{#c92786}{-27x}}=27x+8{\color{#c92786}{-27x}}
