__
<h3>b.</h3>
Put 2 where y is and do the arithmetic.
x = (2 -3(2))/(2 +3) = (2 -6)/5
x = -4/5
Answer:
??!!
Step-by-step explanation:
3 - (5x + 4/5) = x/2
3 - 5x - 4/5 = x/2
3 - 4/5 = x/2 + 5x
15/5 - 4/5 = x/2 + 5x
11/5 = x/2 + 5x.....multiply both sides by 10
22 = 5x + 50x
22 = 55x
22/55 = x
2/5 = x
