Answer:

x = -7/2

Step-by-step explanation:

-3(4x + 9) = 15

Divide 3 on both sides

-3(4x + 9) /3 = 15 /3

Which makes

4x+9=-5

Subtract 9 on both sides

4x+9 -9  = -5   -9

Which makes

4x=-14

So we divide 4

4x  /4 = -14 /4

And we get......

x = -7/2

I hope it's right!

Paige was playing a trivia game where you gained points for correct answers and lost points for incorrect answers. At the start
victus00 [196]

Givens

Start = S = - 700

# Correct = C = 8

Value Correct = VC = 400

# Incorrect =I = 9

Value Incorrect =VI =  - 600

Equation

Score = S + C*VC + I*VI         Substitute

Solve

Score = -700 + 8*400 + 9(-600)

Score = -700 + 3200 - 5400

Score = - 700 - 2200

Score = - 2900 <<<<< Answer
