1. 1.13s - s = _

We are subtracting s from 1.13s. To simplify this equation, we can combine the like terms on the left-hand side (LHS) and solve for the variable.

1.13s - s simplifies to 0.13s.

So, the equation becomes 0.13s = _.

2. d + 2d + d = _

In this equation, we have three terms: d, 2d, and d. To simplify, we can combine the like terms on the left-hand side (LHS).

1d + 2d + 1d simplifies to 4d.

So, the equation becomes 4d = _.
