Answer:
3x + y = -12.
Step-by-step explanation:
y + 3 = 3(x+5)
y + 3 = 3x + 15
3x + 15 = y + 3
3x - y + 15 = 3
3x + y = -12
The answer is:
Answer:
<u>C. 1.05</u>
if u mark as brainly thatll be cool
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
