Answer is x = 7
if u plug in 7 in the second expression, we can get 7 - y = 4, isolate y and then we get 3.
Now, plug in 7 in the first equation to get 2(7) + y = 17. that results to 14 + y = 17. isolate y again and then thats also 3.
so:
x = 7
y = 3
Answer:
1/3 <x
Step-by-step explanation:
2x + 4 < 5x + 3
Subtract 2x from each side
2x-2x + 4 < 5x-2x + 3
4 < 3x+3
Subtract 3 from each side
4-3 <3x-3+3
1 <3x
Divide each side by 3
1/3 <3x/3
1/3 <x
