Weegy: 5(x - 3) + 4(x + 3) = 3(x - 1)
User: Sarah's age is five less than twice her sister's age. Sarah is fifteen years old.
Which equation could you use to solve for the age of Sarah's sister?
2 x - 5 = 15
15 = 5 - 2 x
2(15) - 5 = x
15 - 5 = 2 x
Weegy: Sarah's age is five less than twice her sister's age. Sarah is fifteen years old. 2x - 5 = 15 could be used to solve for the age of Sarah's sister.
User: Solve x/-4 - (-8) = 12.

Weegy: x/-4 - (-8) = 12; x/-4 = 12 - 8; x/-4 = 4; x = -16
(More) 3
To solve the equation x/2 - 3 = 7, we will isolate the variable x by performing the necessary operations.
First, we'll add 3 to both sides of the equation:
x/2 - 3 + 3 = 7 + 3
This simplifies to:
x/2 = 10
Next, we'll multiply both sides of the equation by 2 to eliminate the fraction:
2 * (x/2) = 2 * 10
This gives us:
x = 20
Therefore, the solution to the equation x/2 - 3 = 7 is x = 20.
