Answer: you have to substitute them into the equation
Step-by-step explanation:
example: x = 2y - 6
lets say you test 4/5 so it would be 4 = 2(5) - 6
this equals 4 = 10 - 6 which is true
so that is how you test to see if the equation is right
remember the first number goes to "x" and the second one goes to y
hope this helps mark me brainliest if you can
2(6x+11)-4x=14
12x+22-4x=14
8x=-8
x=-1
y=6(-1)+11
y=5
(-1,5)
The entire shipment contains 9 2/7 tons of sugar
Step-by-step explanation:
- Step 1: Find the total amount of sugar in the entire shipment.
Number of containers in the shipment = 4 1/3 = 13/3
