Answer:
x=6
Step-by-step explanation:
7 + 5(x - 3) = 22
The first step is to distribute the 5
7+ 5x-5*3 =22
7+ 5x-15 =22
Combine like terms
5x-8 =22
Add 8 to each side
5x-8+8 =22+8
5x = 30
5x/5 = 30/5
x=6
Answer:
The Answer is c) 6
Step-by-step explanation:
Solve for x:
5 (x - 3) + 7 = 22
5 (x - 3) = 5 x - 15:
5 x - 15 + 7 = 22
Grouping like terms, 5 x - 15 + 7 = 5 x + (7 - 15):
5 x + (7 - 15) = 22
7 - 15 = -8:
5 x + -8 = 22
Add 8 to both sides:
5 x + (8 - 8) = 8 + 22
8 - 8 = 0:
5 x = 22 + 8
22 + 8 = 30:
5 x = 30
Divide both sides of 5 x = 30 by 5:
(5 x)/5 = 30/5
5/5 = 1:
x = 30/5
The gcd of 30 and 5 is 5, so 30/5 = (5×6)/(5×1) = 5/5×6 = 6:
Answer: x = 6

Step-by-step explanation:
We have xy = 28, x² + y² = 65 and x³ + y³ = 407.
Since (x + y)(x² - xy + y²) = x³ + y³,
x + y = (x³ + y³)/(x² + y² - xy)
= (407) / [(65) - (28)]
= 407 / 37
= 11.
Hence the sum of the numbers is 11.
