Question

I need help with answering 30x + 4 = 86

Answer 1

Question:

Solve the following equation:

30x + 4 = 86​

Solution:

Let the following equation:

$30x\text{ + 4 = 86}$

if we subtract 4 from both sides of the equation we get:

$30x\text{ = 86}-4$

this is equivalent to:

$30x\text{ = }82$

solving for x (divide both sides of the equation by 30), we get:

$x\text{ = }\frac{82}{30}$

this is equivalent to:

$x\text{ = }\frac{82}{30}=\text{ 2.73}$

Then, we can conclude that the correct answer is:

$x\text{ = 2.73}$
