Solve for \( x \):

[tex]\[ 2 = \frac{7}{2}(5x + 6) \][/tex]


Sagot :

Let's solve the equation \(2 = \frac{7}{2}(5x + 6)\) step by step:

1. Eliminate the Fraction:
To get rid of the fraction, multiply both sides of the equation by 2:
[tex]\[ 2 \cdot 2 = \frac{7}{2}(5x + 6) \cdot 2 \][/tex]
[tex]\[ 4 = 7(5x + 6) \][/tex]

2. Distribute the 7 on the Right Side:
Now, distribute the 7 through the parentheses on the right side:
[tex]\[ 4 = 7 \cdot 5x + 7 \cdot 6 \][/tex]
[tex]\[ 4 = 35x + 42 \][/tex]

3. Isolate the Term Involving \(x\):
Subtract 42 from both sides to isolate the term involving \(x\):
[tex]\[ 4 - 42 = 35x \][/tex]
[tex]\[ -38 = 35x \][/tex]

4. Solve for \(x\):
Finally, divide both sides of the equation by 35 to solve for \(x\):
[tex]\[ x = \frac{-38}{35} \][/tex]

5. Simplify the Fraction:
The fraction \(\frac{-38}{35}\) is in its simplest form because the numerator and the denominator have no common factors other than 1. As an approximate decimal value:
[tex]\[ x \approx -1.0857142857142856 \][/tex]

So, the solution to the equation \(2 = \frac{7}{2}(5x + 6)\) is:

[tex]\[ x = \frac{-38}{35} \approx -1.0857142857142856 \][/tex]
