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)
800-500 =300 5 times 100=500 it decreases by 100 each year
I hope that helps
Answer:
3x - 10
Step-by-step explanation:
first set up the like variables next to each other
-4x + 7x - 7 - 3
Then, combine like variables
-4x + 7x = 3x
-7 - 3 = -10
The answer is:
3x - 10
Hello There!
It would be 9(3w + 4) (3w + 4)
Hope This Helps You!
Good Luck :)

33 / 84 ( these digits divide by 3 first we get)
11 / 28 ( after this there is no number from which we can divide these numbers again so)
11 / 28 is the final answer
