what does x= to 4-2x=7x+13
add two x to both sides
4=9x+13
subtract 13 from both sides.
-9=9x
divide both sides by nine.
4-2x=7x+13
add 2x to both sides
4-2x + 2x =7x+13 + 2x
4 = 9x + 13
add -13 to both sides
4 - 13 = 9x + 13 - 13
-9 = 9x
divide both sides by 9
-1 =x
To solve the equation x = 4 - 2x = 7x + 13, you can follow these steps:
1. Simplify the equation by combining like terms. Start by adding 2x to both sides:
4 - 2x + 2x = 7x + 13 + 2x
This simplifies to:
4 = 9x + 13
2. Next, subtract 13 from both sides to isolate the "9x" term:
4 - 13 = 9x + 13 - 13
This simplifies to:
-9 = 9x
3. Finally, divide both sides of the equation by 9 to solve for x:
-9/9 = 9x/9
This simplifies to:
-1 = x
Therefore, the solution to the equation x = 4 - 2x = 7x + 13 is x = -1.
