SAT Question 4f669597: Linear Equations In One Variable answer and explanation with Desmos solution

One way to solve the equation $2(p+1)+8(p-1)=5p$ is to 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 $p=\frac{6}{5}$, which is equivalent to $p=1.2$. Note that 6/5, 1.2, and 1.20 are examples of ways to enter a correct answer.
