Answer:
Step-by-step explanation:
4x + 23 + 9x - 38 = 180
13x - 15 = 180
13x = 195
x = 15
4(15) + 23= 60 + 23= 83
9(15) - 38 = 135 - 38= 97
21y - 1 + 97 = 180
21y + 96 = 180
21y = 84
y = 4
21(4) - 1 = 84 - 1 = 83
3 = -(-y + 6)
First, simplify the brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, add 3 + 6 to get 9. / Your problem should look like: 9 = y
Fourth, switch the side. / Your problem should look like: y = 9
Answer: y = 9
