3x-5(3x-7)= 2(x+9) + 45
You won't learn unless you try these yourself.
Multiply out the term in parentheses, combine the x terms together and the constants together, and then put all the x terms on one side of the = and the constants on the other.

Sure! Let's solve the equation step by step:
1. Distribute the -5 to the terms inside the parentheses:
3x - 5(3x - 7) = 2(x + 9) + 45
3x - 15x + 35 = 2x + 18 + 45
2. Combine like terms on both sides of the equation:
-12x + 35 = 2x + 63
3. Move all the x terms to one side by subtracting 2x from both sides:
-12x - 2x + 35 = 2x - 2x + 63
-14x + 35 = 63
4. Move the constant term to the other side by subtracting 35 from both sides:
-14x + 35 - 35 = 63 - 35
-14x = 28
5. Divide both sides of the equation by -14 to isolate x:
(-14x) / -14 = 28 / -14
x = -2
So the solution to the equation is x = -2.
