Answer:
I'm not exactly sure what you want me to do but try using Symbolab bc it looks really confusing when you write it on here
Step-by-step explanation:
4s = 3r
<span>s = 3/4*r </span>
<span>plug this into the second eqution and solve for the other variable: </span>
<span>2r +5(3/4)r = 23 </span>
<span>23/4*r = 23 </span>
<span>r = 4 </span>
<span>plug this r into the above equation we solved: </span>
<span>s = 3/4*r </span>
<span>s = 3/4*4 </span>
<span>s = 3 </span>
<span>system is: </span>
<span>{r=4, s=3}</span>
1. 4x=64
x=26
2. 9x=20
x=9/20
3. 8+5x<70
5x<62
x<12.4
4. 2+x=50
x=52
5. n+5-5<15
n<15
6. x-10=30
