Francine solves the system of equations using the linear combination method. 4x+3y=−1 3x−5y=4 which steps would allow her to eliminate the x terms in the system of equations? (a) multiply 4x+3y=−1 by 4. multiply 3x−5y=4 by 3. add the resulting equations together. (b) multiply 4x+3y=−1 by 3. multiply 3x−5y=4 by −4 . add the resulting equations together. (c) multiply 4x+3y=−1 by 5. multiply 3x−5y=4 by 3. add the resulting equations together. (d) multiply 4x+3y=−1 by −4 . multiply 3x−5y=4 by 3. add the resulting equations together.

Answer

(B) Multiply 4x+3y=−1 by 3. Multiply 3x−5y=4 by −4 . Add the resulting equations together.

Explanation

There are 2 ways of solving simultaneous equation, substitution and elimination.

In elimination, we either eliminate x or y. For this question, we are eliminating x.

(4x+3y=−1  )× 3

(3x−5y=4 ) × -4

Then add the results as follows.

    12x + 9y = -3

+  -12x + 20y = -16

       0x + 29y = -19

29y = -19

y = -19/29

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
