Answer:
12
Step-by-step explanation:
The proportion is equal to 
We can simplify the right side by dividing by 7/7 to get the right side equal to 6/5. Now we can cross-multiply to get

Dividing both sides by 5, we have the answer as

Answer:
y=5
x=-1
Step-by-step explanation:
5x-2y=-15
3x+8y=37
add 2y to both sides
5x=2y-15
divide both sides by 5
x=(2y-15)/5
x=2y/5-3
substitute for x
3(2y/5-3)+8y=37
6y/5-9+8y=37
add 9 to each side
6y/5+8y=46
subtract 8y from both sides
6y/5=46-8y
multiply both sides by 5
6y=5(46-8y)
6y=230-40y
46y=230
y=5
substitute for y
5x-2(5)=-15
5x-10=-15
5x=-5
x=-1

Answer:
34
Step-by-step explanation:
1. Find the greatest common factor of 26 and 8
Factors of 26 = 2 · 13 = 26
Factors of 8 = 2 · 2 · 2 = 8
The greatest common factor of 26 and 8 is 2.
2. Write the expression as the greatest common factor and a sum
(a) Divide the expression by the greatest common factor

(b) Multiply the sum by 2
26 + 8 = 2(13 +4)
3. Simplify the expression
2(13 +4) = 2(17) = 34
