For this case we must resolve the following inequality:
Applying distributive property on the left side of inequality we have:
Subtracting 5 from both sides of the inequality:
Subtracting 4x from both sides of the inequality:
Thus, the result is 
Answer:
Answer: 325$
Explanation:
Assume: A is the cost of washer
And B is the cost of dryer
A+B = 744
And: A = B + 94$
We get:
B + 94$ + B = 744
2B + 94 = 744
2B = 650
B = 325
50:45, simplified it is 10:9
(Divide both sides by 5)
(5 + 7x + 6)/2 = 3x + 9
7x + 11 = 6x + 18
7x - 6x = 7
x = 7
EF = 3x + 9
= 3(7) + 9
= 21 + 9
= 30
2x+y-3z=12
2x=4z-y
x=2z-y/2
