Solve each system of liner equations y=2x+1 x+2y=17 pls help!

1 answer:

3 0

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>

(((5•(x4))+7x)+2)-((3x2-2x)+9)

Step 2 :

Equation at the end of step 2 :

((5x4 + 7x) + 2) - (3x2 - 2x + 9)

Step 3 :

Checking for a perfect cube :

3.1 5x4-3x2+9x-7 is not a perfect cube

Trying to factor by pulling out :
