$136.40 + $20.46 = $156.86
the value is
1.2r-11.3r=40
-10.Ir=40
r=40/-10.1
r=-0.2525

Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x=
or x=5
Answer:
x=
or x=5
