Find the value of [tex]x[/tex] in each of the following:

a) [tex]\frac{2x}{3} = 8[/tex]

b) [tex]\frac{3x}{2} = 6[/tex]


Sagot :

Sure, let's solve each equation step by step.

### Part (a)
Solve the equation [tex]\(\frac{2x}{3} = 8\)[/tex]:

1. Isolate the variable [tex]\(x\)[/tex]:
To isolate [tex]\(x\)[/tex], first multiply both sides of the equation by 3 to get rid of the denominator:

[tex]\[ 3 \cdot \frac{2x}{3} = 3 \cdot 8 \][/tex]

This simplifies to:

[tex]\[ 2x = 24 \][/tex]

2. Solve for [tex]\(x\)[/tex]:
Now, divide both sides by 2:

[tex]\[ x = \frac{24}{2} \][/tex]

This simplifies to:

[tex]\[ x = 12 \][/tex]

So, the solution to part (a) is [tex]\(x = 12\)[/tex].

### Part (b)
Solve the equation [tex]\(\frac{3x}{2} = 6\)[/tex]:

1. Isolate the variable [tex]\(x\)[/tex]:
To isolate [tex]\(x\)[/tex], first multiply both sides of the equation by 2 to get rid of the denominator:

[tex]\[ 2 \cdot \frac{3x}{2} = 2 \cdot 6 \][/tex]

This simplifies to:

[tex]\[ 3x = 12 \][/tex]

2. Solve for [tex]\(x\)[/tex]:
Now, divide both sides by 3:

[tex]\[ x = \frac{12}{3} \][/tex]

This simplifies to:

[tex]\[ x = 4 \][/tex]

So, the solution to part (b) is [tex]\(x = 4\)[/tex].

### Summary
For the given equations:
- The solution to [tex]\(\frac{2x}{3} = 8\)[/tex] is [tex]\(x = 12\)[/tex].
- The solution to [tex]\(\frac{3x}{2} = 6\)[/tex] is [tex]\(x = 4\)[/tex].
