Answer:
x = 3
Step-by-step explanation:
4x - 5 = 2x + 1
Subtract 2x from both sides;
2x - 5 = 1
Add 5 to both sides;
2x = 6
Divide both sides by 2;
x = 3
X+y=90
x<2y
x+y< 3y
but x+y=90
90<3y
⇒ y>30
for example y=31, then x= 59
y=32, x= 58
.............................................
y=40, x=50
I think the answer would be (70+16n)+(85+13n) !
