130 + 2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
2x + 4y + 54 = 180
2(25) + 4y + 54 = 180
50 + 4y + 54 = 180
4y + 104 = 180
4y = 180 - 104
4y = 76
y = 76/4
y = 19
answer: x = 25 and y = 19
Answer:
3x - 3 = 20
Step-by-step explanation:
Times is a word that represents multiplication. A number can be represented by x.
3x - 3 = 20
Solving this:
3x - 3 = 20 1. Add 3 on both sides
3x = 23 2. Divide by 3 on both sides
x = 7 2/3
