What is the solution for [tex]$x$[/tex] in the equation?

[tex]-2x + 14 + 10x = 34[/tex]

A. [tex]x = \frac{1}{8}[/tex]
B. [tex]x = \frac{5}{2}[/tex]
C. [tex]x = \frac{2}{5}[/tex]
D. [tex]x = 6[/tex]


Sagot :

To solve the equation [tex]\(-2x + 14 + 10x = 34\)[/tex] for [tex]\(x\)[/tex], let's proceed step by step:

1. Combine like terms:
[tex]\[ -2x + 10x + 14 = 34 \][/tex]
Combine [tex]\(-2x\)[/tex] and [tex]\(10x\)[/tex]:
[tex]\[ (10x - 2x) + 14 = 34 \][/tex]
which simplifies to:
[tex]\[ 8x + 14 = 34 \][/tex]

2. Isolate the term with [tex]\(x\)[/tex]:
Subtract 14 from both sides of the equation:
[tex]\[ 8x + 14 - 14 = 34 - 14 \][/tex]
Simplifies to:
[tex]\[ 8x = 20 \][/tex]

3. Solve for [tex]\(x\)[/tex]:
Divide both sides by 8:
[tex]\[ x = \frac{20}{8} \][/tex]
Simplify the fraction:
[tex]\[ x = \frac{20}{8} = \frac{5}{2} \][/tex]

Thus, the correct solution for [tex]\(x\)[/tex] is [tex]\(\frac{5}{2}\)[/tex].

The correct answer is:
[tex]\[ \boxed{B. \, x = \frac{5}{2}} \][/tex]
