Step-by-step explanation:
Answer:x + y = 54
x - y = 10
Add them to get: 2x = 64
x = 32
and plugging in x = 32 to either equation: y = 22
Ans: the numbers are 22 and 32
Step-by-step explanation:
8-4x-7=5x+30-2
combine like terms
1-4x=5x+28
-27=9x
divide both sides by nine
-3=x
Answer:
5
Step-by-step explanation:
3x - 1 = 3(2) - 1
= 6 - 1
= 5
