Answer:
There are infinite solutions
Step-by-step explanation:
Both of these equations are the exact same. 6x+2y=-4 in y=mx+b form is y = -3x - 2. This means that since they are exactly the same, there are infinite solutions.

Answer:
<u>41 years ago</u>
Step-by-step explanation:
Let the no. of years ago be x.
Then, the equation we need would be :
=> 80 - x = 3(54 - x)
=> 80 - x = 162 - 3x
=> 2x = 82
=> x = 41
Sally's mother was 3 times her age <u>41 years ago</u>
Checking
=> Sally = 54 - 41 = 13
=> Mom = 80 - 41 = 39
=> 13 x 3 = 39 [∴Verified]
