I NEED HELP!!! What is is this ----&gt; 3x - 3y = 3 12x + 8y = -8 <br> x = what <br> y = what
fgiga [73]

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

ikadub [295]

Answer:

73.3%

Step-by-step explanation:

We can express 44 out of 60 as 44/60. Since the fraction viniculum means division, this reaches 44 divided by 60.

In doing so, we achieve the answer 73.33333.... terminating.

Rounding to the nearest place gives 73.3 as our answer.
