$\: \: \bullet \quad \red{ \bf{ \underline{ \: according \: to \: the \: question : }}}$

$\: \: \qquad \implies \displaystyle \sf{x + y = 200}$

$\: \: \qquad \implies \displaystyle \sf{ - 150 + y = 200}$

$\: \: \qquad \implies \displaystyle \sf{ - 150 + y - 200} = 0$

$\: \: \qquad \implies \displaystyle \sf{y = 300}$

Answer 2

Answer:

350

Explanation:

Let's take the first integer as 'x'

Let's take the second integer as 'y'

=> x + y = 200

If one of them is -150:

=> -150 + y = 200

By Cross Multiplication:

=> y = 200 + 150 [-150 changes to +150]

=> y = 350

Verification:

(-150) + 350 = 200

Hence, Verified
