3x - x + 3 + x - 5 - x = x + 10
egoroff_w [7]

Answer:

x=12

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−x+3+x−5−x=x+10

Step 1: Simplify both sides of the equation.

3x−x+3+x−5−x=x+10

3x+−x+3+x+−5+−x=x+10

(3x+−x+x+−x)+(3+−5)=x+10(Combine Like Terms)

2x+−2=x+10

2x−2=x+10

Step 2: Subtract x from both sides.

2x−2−x=x+10−x

x−2=10

Step 3: Add 2 to both sides.

x−2+2=10+2

x=12

Two consecutive integers have a sum of 67. What are the two integers?
Eduardwww [97]
<h3>♫ :::::::::::::::::::::::::::::: // Hello There ! //  :::::::::::::::::::::::::::::: ♫</h3>

➷  We can call the first integer 'x'

Thus, the second integer would be 'x + 1'

From this, we can form an equation:

x + x + 1 = 67

Simplify this:

2x + 1 = 67

- 1 from both sides:

2x = 66

Divide both sides by 2:

x = 33

Therefore, x + 1 = 34

The 2 integers are 33 and 34.

➶ Good Luck (:
