Answer:
3. 9x+5+x-7=25
4. 10x-2=25
5. 10x=27
Step-by-step explanation:
3. 9x+5+x-7=25
4. 10x-2=25
10x=25+2
5. 10x=27
x=27÷10
x=2.7
(x + y = 29)
(y = 29 - x)
(5x + 2(29 - x) = 100)
(5x + 58 - 2x = 100)
(3x = 42)
(x = 14)
(y = 15)
(14 5-point questions and 15 2-point questions)
B, because you subtract 9 from both sides(2x-9 leaves 2x by itself then 33-9=24), which leaves you with 2x=24 the you divide everything by 2 which leaves you with x=12
