SAT Mathematics Practice Test 5

To solve the equation 2(p+1)+8(p−1)=5p, first distribute the terms outside the parentheses to the terms inside the parentheses: 2p+2+8p−8=5p. Next, combine like terms on the left side of the equal sign: 10p−6=5p. Subtracting 10p from both sides yields −6=−5p. Finally, dividing both sides by −5 gives p=65=1.2. Either
