Answer:
x=-5
Step-by-step explanation:
25 - 3x = 40
-3x + 25 =40
-3x +25--25=40-25
-3x=15
-3x÷-3=25÷-3
x=-5
<span>y = -3x + 4
x + 1/3y = 4/3
Substitute the first expression into the second equation for y:
</span>x + 1/3(-3x + 4) = 4/3
x - x + 4/3 = 4/3
4/3 = 4/3
Answer;
All real numbers are solutions.
Hope this helps.
