The second equation gives you an expression for y that can be substituted into the first equation.
... 2x + 2(x+3) = 38 . . . . . x+3 substituted for y
... 2x +2x +6 = 38 . . . . . eliminate parentheses
... 4x = 32 . . . . . . . . . . . subtract 6
... x = 8 . . . . . . . . . . . . . . divide by 4
... y = 8 + 3 = 11 . . . . . . . use the second equation to find y
The solution to the system is (x, y) = (8, 11).
Answer:
Step-by-step explanation:
$3x6=18 the six represents the apples and the 3 is the cost of each apple, 18 is the cost.
$2x9=$18 the nine is the oranges and the two is the money spent on each one. The total would be $36 in total for all the fruit.
So (9x2)+(3x6)=$36
(7-2)² - 5/5
Do the math in the parentheses first.
7 - 2 = 5
Now the equation should read
(5)² - 5/5 or just 5² - 5/5
Do the exponent(s).
5² = 25
25 - 5/5
Do the division.
5/5 = 1
25 - 1 = 24
Therefore, according to our equation, the answer is 24.
I hope this answered your question.
