Answer:

$66

Step-by-step explanation:

It can be convenient to assign a different variable to the amount of money each spent. We can call the amounts spent by Seedevi, Georgia, and Amy "s", "g", and "a", respectively.

The problem statement tells us ...

s = (1/2)g

s = a +6

s + g + a = 258

The problem statement asks for the amount Seedevi spent, so we need to find the value of s. It is convenient to write the other variables in terms of s:

g = 2s

a = s -6

Then the sum is ...

s + (2s) +(s -6) = 258

4s = 264 . . . . . . . . . . . add 6, simplify

s = 66 . . . . . . . . . . . . . .divide by 4

Seedevi spent $66.

What are the steps to solving systems of equations and inequalities

Black_prince [1.1K]

Step 1: Line up the equations so that the variables are lined up vertically.

Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.

Step 3: Subtract the two equations.

Step 4: Solve the one variable system.

Step 5: Put that value back into either equation to find the other equation.

Step 6: Reread the question and plug your answers back in to check.
