Question

The root of the equation 3y+10=-2 is -4. Solve the equation

Answer 1

Answer:

Step-by-step explanation:

then y=-4

    3(-4) + 10 =-2

    -12  = -12

0=0

hence proved that -4 is root of equation

Answer 2

Answer:

Step-by-step explanation:

Since the root of the equation is -4, y = -4....(1)

For the equation 3y + 10 = -2

LHS = 3y + 10

Therefore, solving LHS

= 3y + 10

= 3(-4) + 10 [From (1)]

= -12 + 10

= -2

Also, RHS = -2

Hence, LHS = RHS
