Answer :

To solve for [tex]\( x \)[/tex] in the equation [tex]\(\frac{x + a}{b} = 3.5\)[/tex] with the given values [tex]\( a = 22 \)[/tex] and [tex]\( b = 4 \)[/tex], follow these steps:

1. Substitute the given values into the equation:

[tex]\[ \frac{x + 22}{4} = 3.5 \][/tex]

2. Isolate the term containing [tex]\( x \)[/tex] by eliminating the fraction:

Multiply both sides of the equation by 4 to cancel the denominator on the left-hand side:

[tex]\[ 4 \times \frac{x + 22}{4} = 3.5 \times 4 \][/tex]

This simplifies to:

[tex]\[ x + 22 = 14 \][/tex]

3. Solve for [tex]\( x \)[/tex]:

Subtract 22 from both sides of the equation to isolate [tex]\( x \)[/tex]:

[tex]\[ x + 22 - 22 = 14 - 22 \][/tex]

Simplifying this gives:

[tex]\[ x = -8 \][/tex]

Therefore, the value of [tex]\( x \)[/tex] is [tex]\( -8 \)[/tex].
