It is: 34 -5y simplified

4x + 3y = 4 x - 2y = -10, so add 2y to both sides gives x=2y-10, replace this into first equation gives: 4(2y-10) + 3y = 4, expand that gives 8y-40+3y=4, add 40 to both sides, this gives: 8y + 3y =44, or 11y = 44 giving you y=4. You have solved for y, now solve for x: 4x + 3y = 4, gives 4x +12 = 4, or 4x=-8 giving x=-2. So x=-2 and y=4. QED.

You can only simplify, and by the way you wrote it, it is a bit confusing. I'll assume you mean: 8y + 2 - 18y -5. In order to do this you must combine like terms, or the same things. We can combine 8y and -18y, as they are both y. 8y - 18y = -10y. Now we can combine 2 and -5, as they both are plain. 2 - 5 = -3. Your final answer would be: -10y - 3.

9x2 + 48xy + 64y2 = (3x + 8y)2. Since it is a squared number cannot be a prime. We can say that as a perfect square number, it is formed by the sum of 1 and some prime numbers (excluded 2), i.e 1 + 3 + 5 + 7 + 11 + ... n, where n is a prime.

( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer

factors of 2xy-4x+8y-16

2xy - 4x + 8y - 16 can be factored.(2xy - 4x) + (8y - 16)2x(y - 2) + 8(y - 2)Since y-2 is the same as the other, it would turn out like this:(2x + 8)(y - 2):]

2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .

2xy + 4x + 8y + 16 = 2[xy + 2x + 4y + 8] = 2[x(y + 2) + 4(y + 2)] = 2(y + 2)(x + 4)
