so it should be 3x-2 + x = 30
3x-2+2+x = 30+2
3x+x = 32
4x = 32
4x/4 = 32/4
x=8
Correct! Good job! :)
To solve the equation 3x - 2 + x = 30, you can follow these steps:
1. Combine like terms on the left side of the equation: 3x + x = 4x
The equation becomes: 4x - 2 = 30.
2. To isolate the variable x, add 2 to both sides of the equation: 4x - 2 + 2 = 30 + 2.
This simplifies to: 4x = 32.
3. Divide both sides of the equation by 4 to solve for x: (4x)/4 = 32/4.
This simplifies to: x = 8.
So, the solution to the equation is x = 8.
