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.
