Question

check whether y= -2is a solution of the equation 3y -2=y+2​

Answer 1

Answer:

$y = - 2$

• Given equation 3y-2=y+2

y= -2 will be the solution of the equation if 3y-2=y+2 is equal to 0

$3y - 2 = y + 2 \\ \\ 3 \times ( - 2 ) - 2 = - 2 + 2 \\ \\ - 6 - 2 = 0 \\ \\ - 8$

• no

Answer 2

3y-2=y+2

3y-y-2-2=0

now for y=-2,

3×(-2)-(-2)-2-2

=-6+2-4

=-8

Hence y=-2is not a solution of the equation 3y-2=y+2.
