Eq1) 2r+2s=50
eq2) 2r-s=17
solve for s in equation2 (eq2)
-s=17-2r
s=-17+2r
Substitute s into equation1 (eq1)
2r+2(-17+2r)=50
2r-34+4r=50
6r-34=50
6r=50+34
6r=84
r=14
Substitute into either equation and solve for s
2(14)-s=17
28-s=17
-s=17-28
-s=-11
s=11

Answer:
<u>Step 1: Complete the first equation</u>
0.01 is a hundredth, therefore if we have 1.86 then we have 186 hundredths.
<u>Step 2: Complete the second equation</u>
1.86 / 2 = 0.93
0.01 is a hundredth, therefore if we have 0.93 then we have 93 hundredths.
<u>Step 3: Complete the third equation</u>
1.86 / 2 = 0.93
