Answer:
To solve the equation 4a + 3 = 5a - 4, we want to isolate the variable "a" on one side of the equation.
First, we can simplify both sides of the equation by combining like terms:
4a + 3 = 5a - 4
Subtract 4a from both sides:
4a - 4a + 3 = 5a - 4a - 4
Simplify:
3 = a - 4
Next, we can add 4 to both sides of the equation to isolate "a" on one side:
3 + 4 = a - 4 + 4
Simplify:
7 = a
Therefore, the solution is a = 7
