146. ## Math

Solve this equivalent equation 2x-5>1 Do I add 5 to each side so 2x > 6 than x > 3 is the answer?

147. ## Math

Another equivalent equation. -8w + 18 > -22 So, I subtract 18 from each side. make -8w + 18-18 > -22-18 -8W >-40 than w > 5? I don't leave either of the negatives right because negative divided by a negative is positive right?
