Answer:
The Answer Is A
Step-by-step explanation:
Answer: y = 3 or y=7
Step-by-step explanation:
what 2 factors of 21 can equal 10 when added together (1*21- no 3*7- yes)
Factor
y-3=0
y=3
or y-7=0
y=7
Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
