Answer:
4y
Step-by-step explanation:

Answer:
x=2,y=−1
Step-by-step explanation:
Solve for y in the first equation.
y=−9x/11+7/11
0=−2y+10−6x
Replace all occurrences of y with −9x/11+7/11 in each equation.
0=−48(x−2)11
y=−9x11+711
Solve for x in the first equation.
x=2
y=−9x/11+7/11
Replace all occurrences of x with 2 in each equation.
y=−1
x=2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(2,−1)
The result can be shown in multiple forms.
Point Form:
(2,−1)
Equation Form:
x=2,y=−1
ANSWER
x = 4
EXPLANATION
1) 1+4x = 13+x
2) 1+3x = 13
3) 13 - 1 = 12
4) 3x = 12 (Solve for x by dividing 3 on both sides)
5) x = 4
Answer:
Original price reduced by 30%
Step-by-step explanation:
You want the deepest discount, which means you want the greatest percent/amount off. The first choice is 20%. The second is 30%. The third one is 25%, because you are paying for 75% (100-75). The second choice offers the deepest discount because it is 30% off.
