Answer:
3x = 3 + 2y -------------> 3x - 2y = 3 {subtracted 2y from each side of top equation}
(-4/3)x + y = -2/3 ------> -4x + 3y = -2 {multiplied bottom equation by 3}
3x - 2y = 3 ------> 12x - 8y = 12 {multiplied top equation by 4}
-4x + 3y = -2-----> -12x + 9y = -6 {multiplied bottom equation by 3}
12x - 8y = 12
-12x + 9y = -6
--------------
y = 6 {added the two equations}
3x = 3 + 2y {original top equation}
3x = 3 + 2(6) {substituted 6, in for y, into top equation}
3x = 3 + 12 {multiplied}
3x = 15 {added}
x = 5 {divided each side by 3}
x = 5 and y = 6
Step-by-step explanation:
Answer:
Its either A or C
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
You have to evaluate the power and calculate the sum or difference in order to get the answer
Answer:
(3,-2)
Step-by-step explanation:
In order to find the system you have to figure out where the two lines intersect. In this case, the two lines crossed over each other at (3,-2), so that would be the solution to the system.
Hope this helps :)
I think you just have to do 12 times 9 im.not sure
