⋆ Answer:

x = 5

⋆ Step-by-step explanation:

We're asked to solve the following two-step equation

2x + 5 = 15

Recall that the whole idea of solving an equation is isolating the variable, which in this case is x.

Begin by subtracting 5 from both sides :

⇒ 2x + 5 = 15

2x = 10

We still need to divide both sides by 2

⇒ x = 5

So, our result is x = 5.

Answer:

x=5

Explanation:

2x + 5 = 15

We want to solve for x.

2x+5=15

Subtract 5 from each side.

2x+5-5 = 15-5

2x=10

Now divide by 2.

2x/2=10/2

x=5
