I’m not sure but good luck
Answer: 0 = 0
Step-by-step explanation:
8 (x - 4) = 2 (4x - 16)
8x - 32 = 8x - 32
0 = 0
Replace the informations you don't know with letters.
x = number of bags
y = number of sandwiches
7x + 3y = 22
3x + y = 8
Then solve the equations.
First, isolate the y in the second one like this :
y = 8 - 3x
then replace the y in the first equation with its worth from the second equation :
7x + 3(8 - 3x) = 22
solve for x, then replace the value in the equations to get the value of y
Answer:
y = -4/3 x +2/3
Step-by-step explanation:
4x + 3y = 2
Subtract 4x from each side
4x-4x + 3y =-4x+ 2
3y = -4x+2
Divide each side by 3
3y/3 = -4x/3 +2/3
y = -4/3 x +2/3
