y = -x + 4 , y = -3x + 16 . Answer as an ordered pair. (x, y)

Answer is (-3, 7)

Step-by-step explanation:

y = -x + 4 equ 1

y = 3x + 16 equ 2

Make x subject of formular in equ 1

x = 4 - y equ 3

Subatitute x = 4 - y in equ 2

y = 3(4-y) +16

y = 12 - 3y + 16

y + 3y = 12 + 16

4y = 28

y = 28/4 = 7

Substitute y = 7 in equ 1

7 = -x + 4

7 - 4 = -x

x = -3

Answer is (-3, 7)

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
