Answer 3

Sure, let's solve the equation:

290 + x = 640 - 260

First, perform the operations on the right side of the equation:

640 - 260 = 380

Now, the equation becomes:

290 + x = 380

To solve for x, subtract 290 from both sides of the equation to isolate x on one side:

x = 380 - 290

x = 90

So, the value of x that satisfies the equation is 90.
