Solve the system using the addition method. State your solution as an ordered pair.

vladimir1956 [14]

Solution as ordered pair is:

(5, $\frac{41}{2}$ )

Step-by-step explanation:

Solving the system of equations:

$3x+2y=56\,\,\,(1)\\9x-2y=4\,\,\,(2)$

Adding equation(1) and equation(2)

$3x+2y=56\\9x-2y=4\\--------\\12x=60\\x=\frac{60}{12}\\x=5$

Putting value of x i.e x=5 in equation(1)

$3x+2y=56\\3(5)+2y=56\\ 15+2y=56\\2y=56-15\\2y=41\\y=\frac{41}{2}\\y=\frac{41}{2}$

So, value of x=5 and y= $\frac{41}{2}$

Solution as ordered pair is:

(5, $\frac{41}{2}$ )

Help! given 2(x-9)=-10 prove x=4 with statements and reasons

Sedbober [7]

Step-by-step explanation:

Proof:

2 ( x - 9) = - 10 when x = 4

2 ( 4 - 9) = -10

8 - 18 = -10

-10 = -10 ..........hence proven

Reasons 

- When you replace X with 4, you can clearly see that the equation is equal to -10.

sorry I couldn't answer accurately, but I hope this helps

Which of the following is equal to (2x/3 - 7) + 7

diamong [38]

The correct answer is D. The number 7 is subtracted from the first term, 2x/3, but then an equal sum is added, and the two effectively cancel each other out. This means that the value of the first expression is essentially 2x/3, which is option D.
