Question

check whether the value given in the bracket is a solution or not (1) . 2x/5 + 4 = 10 (x = 15)
(2) 4p - 5 = 16 (p = 7)​

Answer 1

Answer:

question no.(1) is correct but question no. 2 is wrong

Answer 2

Answer:

$\frac{2x}{5} - 4 = 10 \\ 2x = 10 - 4 \times 5 \\ 2x = 30\\ x = \frac{30}{2} \\ x = 15$

1 no. verified

$4p - 5 = 16 \\ 4p = 16 + 5 \\ 4p = 21 \\ p = 21 \div 4 \\ p = 5.25$

so this answer is wrong
