Multiply the number in the tens place of the bottom
number by the number in ones place of the top number. So
multiply the 1 by the 5, which makes 5. Multiply the number in
the tens place of the bottom number by the number in tens
place of the top number. Multiply 1 by 2, which equals 2.
First move +5 to to the other side.
-7x=-16-5
-7x=-21
Then after this devide both sides by negative seven.
X=3
