Which equation can be used to solve for [tex]$x$[/tex]?

A. [tex]4x + 76 = 90[/tex]
B. [tex]4x + 76 = 180[/tex]
C. [tex]4 + x = 76[/tex]
D. [tex]4x = 76[/tex]

Solve for [tex]$x$[/tex].

[tex]x =[/tex]

Answer :

We first choose the equation
[tex]$$4x + 76 = 90$$[/tex]
because it is set up so that we can solve for [tex]\( x \)[/tex]. Here is the step-by-step solution:

1. Subtract 76 from both sides:

[tex]$$4x + 76 - 76 = 90 - 76$$[/tex]

This simplifies to:

[tex]$$4x = 14$$[/tex]

2. Divide both sides by 4 to solve for [tex]\( x \)[/tex]:

[tex]$$x = \frac{14}{4}$$[/tex]

Simplifying the fraction gives:

[tex]$$x = 3.5$$[/tex]

Thus, the value of [tex]\( x \)[/tex] is:

[tex]$$x = 3.5$$[/tex]
