Question

check whether the value given against each equation in brackets, satisfy the equation : (a) x+5=7(x=2)
(b)-8+z=4(z=-12)​

Answer 1

Answer:

a) x + 5 = 7

if x = 2

2 + 5 = 7

7 = 7

hence proved

b) - 8 + z = 4

if z = - 12

- 8 + (- 12) = 4

-20 = 4

this value of x is an incorrect root of this equation
