6(4c-3). Find which number is common between both (6) and take it out.
Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation: 
simplify it : 
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
25 girls and 50 boys!!
49 divided by 7 = 7.
So there were 7 adults.
49 + the 1 it mentioned = 50 boys
50 divided in half = 25 girls.
50+25+7 = 82.
