The price of the plow is \$150. The price of the tractor is \$1050.
Let $p$ be the price of the plow. The price of the tractor is $7p$. $p+7p=1200$ $\longrightarrow$combine like terms $8p=1200$ $\longrightarrow$multiplication property $8p\div8=1200\div8$ $\longrightarrow$simplify $p=150$ $7p=7\times150=1050$
