Answer:
The sheet steel costed $22.41 per square meter
Step-by-step explanation:
Y coordinate on solving both equations comes out to be 0
-2x+3y=-6
3y = -6+2x
put the value of 3y in equation 2nd
5x-2(-6+2x) =15
5x+12-4x = 15
x=3
put value of X in 3y = -6+2x
3y = -6+2*3 = -6+6 = 0
thus y = 0
Answer:
1 bag of chips cost $1.25
Step-by-step explanation:
total money spent minus cost of soda = price of 2 bags of chips
