3x-5(3x-7)= 2(x+9) + 45

3x-15x+35= 2x+18 +45
-12x + 35 = 2x+63
-12x -28 = 2x
-12 -28 =x
-40 =x

3x-5(3x-7)= 2(x+9) + 45

3x-15x+35= 2x+18 +45
-12x + 35 = 2x+63
-10x+35=63
-10x=28
x=-2.8

you are both wrong!

3x - 15x + 35 = 2x + 18 + 45
-12x - 2x = 63 - 35
-14x = 28
x = -2

test my answer, it works

18x+13/4-17x-19/36

To solve the given equation 3x - 5(3x - 7) = 2(x + 9) + 45:

Step 1: Distribute the 5 on the left side and the 2 on the right side of the equation:

3x - 15x + 35 = 2x + 18 + 45

Step 2: Combine like terms on both sides:

-12x + 35 = 2x + 63

Step 3: Move all the variables to one side and the constants to the other side:

-12x - 2x = 63 - 35

-14x = 28

Step 4: Solve for x by dividing both sides of the equation by -14:

x = 28 / -14

x = -2

However, it seems that there are different answers provided by different users. Let's test the solution x = -2 to see if it works:

Substituting x = -2 back into the original equation:

3(-2) - 5(3(-2) - 7) = 2(-2 + 9) + 45

-6 -5(-6 -7) = 2(7) + 45

-6 -5(-13) = 14 + 45

-6 + 65 = 14 + 45

59 = 59

The equation is balanced and the solution x = -2 satisfies the original equation. Therefore, the correct solution to the equation is x = -2.
