23 because you subtract your highest number with your lowest number
Here, 0.625x - y = -9.625
y = 0.625x + 9.625
Substitute the value of y in 2nd equation,
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070
Now, substitute it in first equation,
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58
In short, Your Answer would be: (-0.070, 9.58)
Hope this helps!
80.1 years, im not 100% sure of my answer though
1st use the Step! Please, Excuse, My, Dear, Aunt, Sally! Ehich also means (PEMDAS) Parenthesis (), Exponents ", Multiple ×, Division÷, Addition+, and Subtraction-. Than your going to solve! (3n+5)×9=n×7
27n+45=7n
27n-7n=-45
20n=-45
n=-45/20= -9/4
