Ответ:
x/y=1/4
Step-by-step explanation:
3x+2y=3y-2
3x=3y-2y-2
3x=y-2
y=3x+2
x+y=10
x+3x+2=10
4x+2=10
4x=10-2
4x=8
x=8/4
x=2
2+y=10
y=10-2
y=8
x/y=2/8=1/4
Ответ:
One solution.
Step-by-step explanation:
So we have:
2x + 3 = 4x + 2
Simplifying gives;
4x - 2x = 3 - 2
2x = 1
x = 1/2
There is only one solution here.
*Note: This questions are simple. You just have to do a little more practice on algebra if you are stuck.
