Answer:
Step-by-step explanation:
7x +3 = 4x -9
7x - 4x = -9 -3
3x = -12
X = -12/3
x = -4
The solution to the equation 7x + 3 = 4x - 9 is x = -4
The given equation is:
7x + 3 = 4x - 9
Collect like terms by subtracting 4x from both sides
7x - 4x + 3 = 4x - 4x - 9
3x + 3 = -9
Subtract 3 from both sides
3x + 3 - 3 = - 9 - 3
3x = -12
Divide through by 3
3x / 3 = -12 / 3
x = -4
The solution to the equation 7x + 3 = 4x - 9 is x = -4
