Answer:

I'm not sure to help you but I can help you out a bit.

Since x - 2y = 1,

x = 1+ 2y

This is expressing x in terms of y.

In addition,

2y = x - 1

y = (x-1)/2

This is expressing y in terms of x.

Answer:

LP = 18

Step-by-step explanation:

Given that,

In ΔLPN,

LQ = 6, LM = 11 and MN = 22

We need to find the length of LP.

As QM ║PN, let QP = x

$\dfrac{LQ}{LP}=\dfrac{LM}{LN}\\\\\dfrac{6}{6+x}=\dfrac{11}{11+22}\\\\\dfrac{6}{6+x}=\dfrac{11}{33}\\\\198=66+11x\\\\198-66=11x\\\\132=11x\\\\x=12$

LP = 6+x

= 6+ 12

= 18

Hence, the length of LP is 18.

To eliminate the terms and solve for y in the fewest steps, by which constants should the equations be multiplied by before addi

Alex17521 [72]

Answer:

The first equation should be multiplied by - 7 and the second equation by 3

Step-by-step explanation:

Indeed, let s multiply the first equation by -7

-7*9x-7*3y=7*18

and the second one by 3

3*8x+3*7y=3*10

when we add both the terms in y will be -7*3y+3*7y= 0

and then we can solve on x

hope this helps
