7x+3=7x+b

b=3 after you subtract 7x from both sides.

7x + 3 = 7x + b

b = 7x-7x+3 = 3

To solve the equation 7x+3=7x+b, we need to isolate the variable x on one side of the equation. Let's go step by step to solve for x.

First, simplify both sides of the equation by combining like terms. The terms involving x on both sides will cancel out.

7x + 3 = 7x + b

Next, we want to move all terms involving x to one side of the equation. Since there is a 7x term on both sides, they will cancel out when we subtract 7x from both sides.

(7x - 7x) + 3 = (7x - 7x) + b

Simplifying further:

0x + 3 = 0x + b

The 0x terms disappear since any number multiplied by 0 is always 0. The equation now becomes:

3 = b

Finally, we have solved for x. The value of x does not affect the equation since the x terms cancelled out during the simplification process. The value of b is equal to 3.

Therefore, there is no specific solution for x, and b equals 3.
