Answer 1

Please let me know if anything I say is confusing. We want to help you learn.

you have a 4-sided shape with 4 right angles, which makes this a rectangle.

that means opposite sides are equal.

now, notice how "10+2x" and "18" are on opposite sides. therefore, 10 + 2x and 18 are equal

therefore, 10 + 2x = 18

can you solve for x from here? let me know if you're still stuck
