Question

7. Pick the solution from the values given in the bracket next to the equation. Show that the other values do not satisfy the equation.

(a) q/2=7 ;(7,2,10,14)

(b) 3x+16=4 ;(3,-3,4,-4​

Answer 1

Step-by-step explanation:

$\frac{q}{2} = 7$

$q = 14$

$3x + 16 = 4$

$3x = - 12$

$x = - 3$

Answer 2

Answer:

5m=60

⇒m=

5

60

=12

Hence the value of m=12.

Now,

For m=10

5×10=50



=60

For m=5

5×5=25



=60

For m=15

5×15=75



=60
