Answer:

Hello!

~~~~~~~~~~~~~~~``

Simplifying

2x + 3y = 45

Solving

2x + 3y = 45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

2x + 3y + -3y = 45 + -3y

Combine like terms: 3y + -3y = 0

2x + 0 = 45 + -3y

2x = 45 + -3y

Divide each side by '2'.

x = 22.5 + -1.5y

Simplifying

x = 22.5 + -1.5y

Hope this helped you! Brainliest would be nice.

What is the answer to: 7(w+2)+0.5w=5
Zepler [3.9K]
First, distribute the 7:

7w + 14 + 0.5w = 5

Combine like terms:

7.5w + 14 = 5

7.5w = -9

Divide both sides by 7.5 to solve for w:

w = -9/7.5 = -1.2

The answer is -1.2
