[tex]\[ VX = 5x + 9 \][/tex]

What is the value of [tex]\( x \)[/tex]?

A. [tex]\( 7 \)[/tex]
B. [tex]\( -7 \)[/tex]
C. [tex]\( 35 \)[/tex]
D. [tex]\( -17 \)[/tex]


Sagot :

To find the value of [tex]\( x \)[/tex] given the equations [tex]\( TV = 10x - 26 \)[/tex] and [tex]\( VX = 5x + 9 \)[/tex], we need to set the two expressions equal to each other and solve for [tex]\( x \)[/tex].

1. Start with the given equations:
[tex]\[ TV = 10x - 26 \][/tex]
[tex]\[ VX = 5x + 9 \][/tex]

2. Set [tex]\( TV \)[/tex] equal to [tex]\( VX \)[/tex]:
[tex]\[ 10x - 26 = 5x + 9 \][/tex]

3. To eliminate [tex]\( 5x \)[/tex] from the right side, subtract [tex]\( 5x \)[/tex] from both sides:
[tex]\[ 10x - 5x - 26 = 5x - 5x + 9 \][/tex]
Simplify the expressions:
[tex]\[ 5x - 26 = 9 \][/tex]

4. To isolate [tex]\( 5x \)[/tex], add 26 to both sides:
[tex]\[ 5x - 26 + 26 = 9 + 26 \][/tex]
Simplify the expressions:
[tex]\[ 5x = 35 \][/tex]

5. Divide both sides by 5 to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{35}{5} \][/tex]
[tex]\[ x = 7 \][/tex]

Therefore, the value of [tex]\( x \)[/tex] is [tex]\( 7 \)[/tex]. The correct answer is [tex]\( 7^\circ \)[/tex].
