If the equations are 2y + 2x = 20 and y - 2x = 4,then the solution is (2, 8).
2x+7y=29 x=37-8y
Without any equality signs they can't be considered to be equations. But if you mean: x+2y =12 and y = x+3 then the solution is as follows x+2y = 12 -x+y = 3 Adding the equations together: 3y = 15 and y = 5 By substitution: x = 2 Solution: x = 2 and y = 5

No because there are no equations there to choose from.

-x+y=12is the equation of a line and since there are infinitely many points on the line and each point is represented by an ordered pair, we have infinitely many solutions.If we take x as 0, then y must be 12so (0,12) is one ordered pair that is a solution to the equation.Zero is often a nice number to pick since it makes the calculation a bit easier.
That is the correct spelling of the verb "to choose" (the past tense is chose).
It depends upon the leaving group, that catalyst is suitable which has the attraction towards leaving group.
OK
Choose is the correct spelling for the present tense.
That is correct
