3x+(-4)=2x+9
To solve this for x.....
3x + (-4) = 2x + 9
3x - 4 = 2x + 9
Add 4 to both sides of the equation.
3x = 2x + 9 + 4
3x = 2x + 13
Subtract 2x from both sides of the equation.
3x - 2x = 13
x = 13
12=6/7x
12 = \(\frac67\)x
Multiply both sides of the equation by \( \frac76 \)
12 * \( \frac76 \) = \(\frac67 \)x * \( \frac76 \)
14 = x
The answer is x=13
