The answer is the top right because it divided by three
Multiple (5x+y= 28) by 6 giving you 30x +6y =168 and then you would add the two equations together, giving you 38x = 152, divide both sides by 38, giving you 4. after this, you would sub x=4 into one of the equations (i’m using the 5x+ y =28) which would give me 20 + y = 28, subtract 20 by both sides, giving you y= 8. so your answer is (4,8)
7/9-1/3 or 7/9-3/9= 4/9 is the answer
Answer:
n = 75
Step-by-step explanation:
Step 1: Write equation
-n = -75
Step 2: Divide both sides by -1
n = 75
Step 3: Check
<em>Plug in n to verify it's a solution.</em>
-75 = -75
