How many solutions does the system x + y = 3 and 2x + 2y = 5 have?

no solution.

Step-by-step explanation:

The given system of equations is

If two equations are defined as , and , then lines are parallel.

In the given equations .

So, the lines are parallel and parallel lines neven intersect each other.

Therefore, the given system of equation have no solution.

if x decreases by 4 then y increases by 10

step-by-step explanation:

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction
