First split up the equation.
(-5×7) + (9 × 5/5)
We know that 5/5 is equal to 1, so replace 5/5 with 1.
(-5×7) + (9 × 1)
Now solve the first part. (Remember, a negative times a positive is always a negative)
-5 × 7 = -35
Now solve the second part.
9 × 1 = 9
Add.
(-35 + 9 equals the same as 35 - 9, but negative)
-35 + 9 = -26
-5 × 7 + 9 × 5/5 = -26
