Answer:

Step-by-step explanation:

x + y = 5

y = 3x + 1

x + 3x + 1 = 5

4x + 1 = 5

4x = 4

x = 1

1 + y = 5

y = 4

Elodia [21]

(6,-5)(9,r)

(r - (-5) / (9 - 6) = -4
(r + 5) / 3 = -4
r + 5 = -4 * 3
r + 5 = -12
r = -12 - 5
r = - 17 <===

To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of

babymother [125]

Answer:

The value of y is $y=\frac{42}{17}$

Step-by-step explanation:

we have

$4x+3y=6$ -----> equation A

$18x+5y=6$ -----> equation B

To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides

I choice

Multiply the equation A by -18/4 both sides

$(-18/4)[4x+3y]=6*(-18/4)$

$-18x-13.5y=-27$ ------> equation C

Adds equation B and equation C

$18x+5y=6\\-18x-13.5y=-27\\-------\\5y-13.5y=6-27\\-8.5y=-21\\\\ y=\frac{42}{17}$
