Seems like the answer is going to come nuts. still I hope this is the answer. pls refer to the attached picture. and mark me BRAINLIEST if it's ok...!

Answer 2

Answer:

x= 2

Step-by-step explanation:

x= 2y=1

\begin{lgathered}2x + 3y = 7 - - - - - (1)\\ 3x + 4y = 10 - - - - - (2)\end{lgathered}

2x+3y=7−−−−−(1)

3x+4y=10−−−−−(2)

multiply first equation with 3 and second equation with two

\begin{lgathered}6x + 9y = 21 - - - - (3) \\ 6x + 8y = 20 - - - - (4)\end{lgathered}

6x+9y=21−−−−(3)

6x+8y=20−−−−(4)

y =1

substitute the value of Y in the first equation

\begin{lgathered}2x + 3 \times 1 = 7 \\ 2x + 3 = 7 \\ 2x = 7 - 3 = 4 \\ x = \frac{4}{2} = 2\end{lgathered}

2x+3×1=7

2x+3=7

2x=7−3=4

x=
