Answer: 35
Explanation:
Alright, so to start with, we have the equation you gave: 4x-5.
Since x = 10, we can replace x with 10 in this equation, so it becomes 4 x 10 - 5.
Using BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction), we start with the multiplication first, so since 4 x 10 = 40, we go from (4 x 10) -5, to 40 - 5
And now moving on to subtraction, 40 - 5 = 35. Hope this helps!
