Question

solve 3x-4y=7 and 2x+3y=-1 ​

Answer 1

Answer:

ans 50

Step-by-step explanation:

Answer 2

Step-by-step explanation:

From the second equation, 2x=3y-1, so x=(3y-1)/2.

Substitute for x in the first equation:

3(3y-1)/2+4y=7, multiply each side by 2:

3(3y-1)+8y=14, 9y-3+8y=14, 17y=17, y=1, therefore x=(3-1)/2=2/2=1.

Solution: x=1, y=1.
