Question

check if the value of the following is the root of the equation 7x - 15 = 6 (x = 4)​

Answer 1

Answer:

of x=4 is a root of equation 7x-15=6 then it will satisfy the equation.

$7x - 15 = 6$

$7(4) - 15 =6$

$28 - 15 - 6 = 0$

$28 - 21$

$28 - 21 = 7 \: is \: not \: equal \: to \: 0$

•°•x=4 is not a root of equation 7x-15=6

the root of equation is

$7x - 15 = 6$

$7x = 6 + 15 = 21$

$x = \frac{21}{7}$

•°•x=3 is a root of the equation 7x-15=6
