Answer:
x=-22
Step-by-step explanation:
7(x–1)–5(2x+2)=49
7x-7-10x-10=49
-3x-17=49
-3x=66
x=-22
4x3x = 12x
4x2 = 8
So 12x+8-2
What is the LCM of 8, 15, and 24? 120
That means, it would be 120 minutes before they are together again.
120 minutes after 3 pm is 5:00 pm
I'm assuming this is a system of equations you want solved so,
x = -y + 3
-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2
x + 2 = 3
x = -1
(-1,2)
