Answer:
Step-by-step explanation:To solve the literal equation ax + b = c for x, you would typically want to isolate x on one side of the equation. The appropriate restriction in this case is that 'a' should not be equal to 0, because if 'a' were equal to 0, you would have 0x + b = c, which simplifies to b = c. This would mean there's no 'x' variable to solve for, and the equation would have no solution or would be true for any value of 'c'. So, the restriction is that 'a' must be nonzero for the equation to be solvable for 'x'.
