$3x + 4y = 10$
​

Answer 1

Answer:

$\huge{\bf{\underline{\red{Answer :}}}}$

↪️Let's just add y to both sides to solve for x in terms of y We get,

x = y + 1

↪️We can plug this value of x into the first equation in the system. We get,

3(y + 1 ) + 4y = 10

↪️Distributing the 3 to both terms in the parenthesis, we get,

3y + 3 + 4y = 10

↪️Combining like terms, we now have

7y + 3 = 10

↪️Subtracting 3 from both sides, we get

7y = 7

↪️Dividing both sides by 7 we find that,

$\boxed{\red{y = 1}}$

↪️We can plug this value into the blue expression to get,

x = 1 +1

Answer:-

$\Rightarrow$ $\boxed{\red{x = 2 }}$
