Answer: 2x-6
Work Shown:
john = x
sam = x-3 since he scored 3 fewer than john
rob = 2*(sam) = 2(x-3) = 2*x-2*3 = 2x-6
Answer: The value of 7P4 is 28
x=0 .
−2(8+8x)+7x=−7x+2(x−8)
Step 1: Simplify both sides of the equation.
−2(8+8x)+7x=−7x+2(x−8)
(−2)(8)+(−2)(8x)+7x=−7x+(2)(x)+(2)(−8)(Distribute)
−16+−16x+7x=−7x+2x+−16
(−16x+7x)+(−16)=(−7x+2x)+(−16)(Combine Like Terms)
−9x+−16=−5x+−16
−9x−16=−5x−16
Step 2: Add 5x to both sides.
−9x−16+5x=−5x−16+5x
−4x−16=−16
Step 3: Add 16 to both sides.
−4x−16+16=−16+16
−4x=0
Step 4: Divide both sides by -4.
−4x
