Question

2x + 4 > 16 is an equation.
True
False




7. Find the value of x in 6x - 5 = 13. * 1 point x = 3 x = 1 x = -1 x = -3​

Answer 1

Answer:

1.false

e.g. x+y=3

Step-by-step explanation:

7.x= 3

answer is x = 3

Answer 2

Answer:

$\sf \green {1. \: False}$

$\sf \green {2. \: \therefore, \: x = 3 \: is \: the \: solution \: for \: the \: given}$ $\sf \green {equation.}$

Step-by-step explanation:

1. Because, it is mentioned 2x + 4 > 16.

2. i) If, x = 3

6 × 3 - 5 = 13

18 - 5 = 13

13 = 13

ஃ, x = 3 is the solution for the given equation.

ii) If, x = 1

6 × 1 - 5 = 13

6 - 5 = 13

1 ≠ 13

ஃ, x = 1 is not the solution for the given equation.

iii) If, x = -1

6 × ( -1 ) - 5 = 13

( -6 ) - 5 = 13

( -6 ) + ( -5 ) = 13

-11 ≠ 13

ஃ, x = -1 is not the solution for the given equation.

iv) If, x = -3

6 × ( -3 ) - 5 = 13

( -18 ) - 5 = 13

( -18 ) + ( -5 ) = 13

-23 ≠ 13

ஃ, x = -3 is not the solution for the given equation.
