5/2y - 8
Step-by-step explanation:
Step 1: Add -7 to both sides.
2x+7+−7=5y−9+−72x=5y−16

2x2=5y−162x=52y−8
Answer:
½ and 14/28
Step-by-step explanation:
If a pair of ratio forms a proportion, they are equal.
First pair of ratios:
4/5 =10/13
Convert to the least common denominator (4 × 13)/65 = (10 × 5)/65
52/65 ≠ 50/65
The first pair of ratios is <em>not</em> a proportion.
Second pair of ratios:
7/8 =15/18
Convert to the least common denominator (7 × 9)/72 = (15 × 4)/72
63/72 ≠ 60/72
The second pair of ratios is <em>not</em> a proportion.
<em>Third pair of ratios:
</em>
½ =14/28
Convert to the least common denominator (1 ×14)/28 = 14/28
14/28 = 14/28
½ = 14/28
½ and 14/28 form a proportion.
