first, take out the x on the right side and move it to the left side (subtract the 13x from 13x and subtract 13x from -2x). then amove 23 from the left side to the right side (add 23 to 23 and add 23 to 22). the equation should be -15x = 45 now. divide -15 from both sides and you should get x = -3!
We use unit rate in every day life, for example, when comparing prices at stores. One store may offer five bowls for $7.99 and the other one bowl for $2.45.
