60 - 20 + 70 = 110
-1 + 4x + 6x - 20 =10x - 19

That depends what the value of x is.
The expression "6x plus 20" can be written mathematically as 6x + 20. It represents a linear equation where the value depends on the variable x. Without a specific value for x, the expression cannot be simplified further into a numerical answer. If you have a specific value for x, you can substitute it in to find the total.
-1 + 4x + 6x - 20 =10x - 19
(5n - 20) It's a binomial expression in 'n'. Its numerical value depends on the numerical value of 'n'.
70
20
That depends what the value of x is.
20
-20 negative 20 minus 20
s - 20
x2 - 9x + 20 = (x - 4)( x - 5)
That will depend on the plus or minus value of 20 or perhaps there is an equality sign missing and so therefore it has no solution.
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
Zero
