Factors are (7y - 3)(7y - 2) so it's not a perfect square.
-35y-134 = -29 -35y = 134-29 -35y = 105 y = -3
no.

Multiply the given fraction by 7y/7y. That's the same as ' 1 ',and it'll give you the denominator of 35y .
With great difficulty, do you mean 35y = 9y-2? If so then the solution is simple: 35y = 9y-2 35y = (32)y-2 35y = 32y-4 Divide both sides of the equation by 3 to eliminate the integers 5y = 2y-4 5y-2y = -4 3y = -4 Divide both sides by 3 to find the value of y y = -4/3 Substituting into the original equation: 35y = 6.594648241 x 10-4 9y-2 = 6.594648241 x 10-4 Therefore: y = -4/3 is correct.
-35y-134 = -29 -35y = 134-29 -35y = 105 y = -3
3x+y=5(4x-7y)=-10 3x+y=20x-35y=-10 -3x -3x y=17x-35y=-10 -y -y 17x-36y=-10 sorry but that's as far as i could get :(
no.

To find an expression equivalent to -28xy 35y, we can first simplify by multiplying the coefficients -28 and 35 to get -980. Then, we multiply the variables x and y to get xy^2. Therefore, the expression equivalent to -28xy 35y is -980xy^2.

-38y - 39x (Is that what you were asking for?)
To find the product of the expressions ((4x - 5y + 3)) and ((2x + 7y - 7)), apply the distributive property (also known as the FOIL method for binomials). When multiplied, you get: [ (4x)(2x) + (4x)(7y) + (4x)(-7) - (5y)(2x) - (5y)(7y) - (5y)(-7) + (3)(2x) + (3)(7y) + (3)(-7) ] Combining all the terms results in: [ 8x^2 + 28xy - 28x - 10xy - 35y^2 + 35 + 6x + 21y - 21 ] Combining like terms yields: [ 8x^2 + (28xy - 10xy) + (-28x + 6x) + (-35y^2 + 21y) + (35 - 21) ] The final simplified expression is: [ 8x^2 + 18xy - 22x - 35y^2 + 14 ]
The 'answer' is usually the number for 'y' that makes the whole statement true.Let's look for it. Actually, the way this works, I'll look for it, while you just watch:-4y + 7 = 35y - 6Add 4y to each side:7 = 39y - 6Add 6 to each side:13 = 39yDivide each side by 39:13/39 = 1/3 = yI think we've found it.
The answer is (2y+3)/(7y-1) but I don't understand why the y stays if y^2 - y^2 equals 0 since the y's cancel out. Please help me understand.
