Question

PLEASE HELP ITS DUE NOW!!!!!! WILL MARK BRAINLIEST!!!!!

Answer 1

Answer:

(- 4, - 10 )

Step-by-step explanation:

y = 5x + 10 → (1)

y = 4x + 6 → (2)

Substitute y = 5x + 10 into (2)

5x + 10 = 4x + 6 ( subtract 4x from both sides )

x + 10 = 6 ( subtract 10 from both sides )

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (1)

y = 5(- 5) + 10 = - 20 + 10 = - 10

solution is (- 4, - 10 )

Answer 2

>> Answer

__________

$\:$

$\sf{y = 5x + 10...(1)}$

$\sf{y = 4x + 6...(2)}$

• Subtitute (1) to (2)

$\sf{y = 4x + 6}$

$\sf{5x + 10 = 4x + 6}$

$\sf5x - 4x = 6 - 10$

$\sf{x = - 4}$

.

• Subtitute x = -4 to (1)

$\sf{y = 5x + 10}$

$\sf{y = 5( - 4) + 10}$

$\sf{y = - 20 + 10}$

$\sf{y = - 10}$

.

$\longmapsto \sf{( - 4 , - 10)}$
