Answer:
5y = 5
Step-by-step explanation:
-2(x -2y) +(2x +y) = -2(-1) +(3) . . . . -2 times [eq2] + [eq1]
-2x +4y +2x +y = 2 +3 . . . . eliminate parentheses
5y = 5 . . . . . . . . collect terms

Answer:

Step-by-step explanation:
The time in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.
t = va
We need to find the expression for d in terms of t and a.
As velocity = distance/time

So, the distance d is
.
