7.3in have a nice dayyyyyy
57.7r + 23.23 =2.57
Subtract 23.23 from both sides:
57.7r = -20.66
Divide both sides by 57.7
r = -20.66 / 57.7
r = -0.358
round to nearest tenth = 0.4
Answer: x = 38.4
Step-by-step explanation:
7-x/3 = -1-x/8
1. Add 1 to both sides
8-x/3 = -x/8
2. Add x/3 to both sides
8 = x/3 - x/8
3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient
8 = 8x/24 - 3x/24
4. calculate the difference between 8x/24 - 3x/24
8 = 5x/24
5. Multiply both sides by 24/5, and there is the answer
38.4 = x
