Question

yreese is using algebra tiles to solve the equation below.

2 x + 5 = negative x + (negative 1)

Tyreese’s first step is to
remove one x-tile from both sides.
remove two x-tiles from the left side.
add one positive x-tile to both sides.
add two positive x-tiles to both sides.

Answer 1

Add one positive x-tile to both sides.

Reason: the right side has a negative x tile (−x), so adding a +x tile to both sides cancels it on the right: 2x+5 becomes 3x+5 and −x−1 becomes −1, which isolates the variable on one side.
