Final answer:
To find the value of x when two expressions (4x + 30) and (5x) are set to be equal, set them equal to each other and solve for x, resulting in x being 30.
Step-by-step explanation:
The question poses two equations that are set to be congruent, or equal: (4x + 30) and (5x). To find the value of x, we need to set these equations equal to each other and solve for x. The solution is obtained by following these steps:
Set the two expressions equal to each other: 4x + 30 = 5x.Subtract 4x from both sides to get the variable terms on one side: 30 = 5x - 4x.Simplify the equation: 30 = x.
The value of x in this case is 30.
