Plug y=2x+1 into <span>x+2y=17, we have:
x+ 2(2x+1)= 17
</span>⇒ x+ 2*2x+ 2*1= 17 (distributive property)
⇒ x+ 4x+ 2= 17
⇒ 5x= 17-2
⇒ 5x= 15
⇒ x= 15/5
⇒ x= 3
<span>
y= 2x+1= 2*3+1= 7
Final answer: x= 3, y= 7~</span>

Answer:
11 1/2
Step-by-step explanation:
23÷2=11 with the reminder of 1
1. 8(-18d-10) = -144d-80
2. -13+14(-18+10d) = -13-252+140d = -265+140d
3. 15(-7x-3) = -105x-45
The number are quite weird but we have to deal with them.
