Answer 1

Step-by-step explanation:

• 1. Given that, x=10
• So, x+10 = 30 =>10+10= 30 => 20 is not = 30.
• Solution = No
• 2.Given that, x = 5
• So, p-3 = 7 here value of p is not given.
• Solution = No
• 3. Given that, m= 2
• So, 2m+3 = 7 => 2*2+3 = 7 => 7=7
• Solution = Yes
• 4. Given that, t = 20
• So, t/5 = 4 => 20/5 = 4 => 4=4
• Solution = Yes

Answer 2

Answer:

$\huge\colorbox{yellow}{Solution\:-}$

$1) \: \: \: x + 10 = 30$

Putting the value of x in x + 10 = 30

$10 + 10 = 30$

$20 = 30$

$\boxed{\pink{NO}}$

$2) \: \: p - 3 = 7$

Putting the value of p in p - 3 = 7

$5 - 3 = 7$

$2 = 7$

$\boxed{\pink{NO}}$

$3) \: \: \: 2m + 3 = 7$

Putting the value of m in 2m + 3 = 7

$2 \times 2 + 3 = 7$

$4 + 3 = 7$

$7 = 7$

$\boxed{\pink{YES}}$

$5) \: \: \: \frac{t}{5} = 4$

Putting the value of the in t/5 = 4

$\frac{20}{5} = 4$

$4 = 4$

$\boxed{\pink{YES}}$
