5x - y = 6<br> -2x +y = 8<br> What’s the answer

nevsk [136]

Answer:

x= $4\frac{2}{3}$

y= $17\frac{1}{3}$

Step-by-step explanation:

$5x-y=6\\-2x+y=8\\$

Simplify, find the x-value first:

$3x=14\\x=4\frac{2}{3}$

Substitute x-value into any equation (i did the second equation) and simplify:

$-2(4\frac{2}{3})+y=8\\ -9\frac{1}{3} +y=8\\$

$y=17\frac{1}{3}$

Raphael graphed the system of equations shown. y = – 3 y = x – 0.8 What is the best approximation for the solution to this syste

Ber [7]

Given ---›

y = -3

&

y = x - 0.8

So,
=> x = y + 0.8

=> x = -3 + 0.8

=> x = -2.2

Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)

Solve this system of equations: -8x+4y=16; y=5x+1 *

SCORPION-xisa [38]

Answer:

x=1, y=6. (1, 6).

Step-by-step explanation:

-8x+4y=16

y=5x+1

----------------

-8x+4(5x+1)=16

-8x+20x+4=16

12x+4=16

12x=16-4

12x=12

x=12/12

x=1

y=5(1)+1=5+1=6
