Question

What is the first step in solving this equation for x : −3 = x over 4 + 2 .

Answer 1

okay but please just tell me the first step

Answer 2

Jonny is solving this equation for n : 8 + 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?

8 is the first term in the equation.

He needs to reverse the order of operations.

He needs to follow the order of operations.

8 is attached to 3 n by subtraction.

Answer 3

To solve the equation -3 = x/4 + 2, we can begin by isolating the term with the variable x.

First, we need to get rid of the constant term on the right side of the equation. We can do this by subtracting 2 from both sides of the equation:

-3 - 2 = x/4 + 2 - 2

Simplifying the left side gives us:

-5 = x/4

Next, we need to remove the fraction by multiplying both sides of the equation by 4:

4 * -5 = 4 * (x/4)

-20 = x

Therefore, the solution to the equation is x = -20.

Answer 4

The first step is to subtract 2 from both sides of the equation to eliminate the constant term:

-3 - 2 = x/4 + 2 - 2

Answer 5

The reason Jonny subtracted 8 from both sides of the equation is to isolate the variable term (3n). By subtracting 8 from both sides, he is eliminating the constant term (8) from the left side of the equation so that only the variable term remains on that side. This step is done in order to simplify and solve for the variable.
