Ответ:
the answer is (x,y) = (2,-1)
Step-by-step explanation:
hope this helps plz put me as brainiest :)
Ответ:
3x + 4y=2
Move 4y to the right-hand side and change its sign into -4y. So should now be 3x=2-4y.
Then, divide both sides of the equation by 3. So it should look like x= 2/3 -4/3y.
And that’s your final answer. (x=2/3 -4/3y)
Finding Y:
3x +4y=2
Move 3x to the right-hand side and change it’s sign, so it should now look like 4y=2-3x.
Then you divide both sides of the equation by 4, should now it should look like y=1/2-3/4x, and that’s you final answer for solving for y.
Hope these helped! :)
