The only valid answer is adding 4.3 x to both sides of the equation. All of the other choices would not help you solve for x.
Answer:
B. Add [tex]4.3x[/tex] to both sides of the equation.
Step-by-step explanation:
We have been given an equation [tex]3.7x-18=-4.3x-34[/tex]. We are asked to choose the most efficient first step to solve for x in the equation.
To solve an expression we need to separate variables and constants on different sides of equation.
To solve our given equation we need to add [tex]4.3x[/tex] to both sides of the given equation. After adding [tex]4.3x[/tex] we will get,
[tex]3.7x+4.3x-18=-4.3x+4.3x-34[/tex]
[tex]8.0x-18=-34[/tex]
Therefore, option B is the correct choice.
