Answer:
I'm assuming that this is supposed to be in algebraic expression form.
Step-by-step explanation:
The <em>product of 6 and a number</em> is expressed as <em>6x.</em> So the expression of 6x less than (use minus symbol) 20, should be written as 6x - 20.
Hope it helps.
We will multiply both sides of an equation by 6 z :


2=-5z+1
2-1=-5z
1=-5z
50 x 9 = 450
450 - 4 = 446
446 - 7 = 439
It's 36!!!! hope that helped
