2x - 3y = 4
This can't be solved, although you can express each variable in terms of the other.
x = (4-3y)/2
y = (2x-4)/3
Here is the 4 times table up to 12: 1 times 4 equals 4 2 times 4 equals 8 3 times 4 equals 12 4 times 4 equals 16 5 times 4 equals 20 6 times 4 equals 24 7 times 4 equals 28 8 times 4 equals 32 9 times 4 equals 36 10 times 4 equals 41 11 times 4 equals 44 12 times 4 equals 48

y = 3x = 12y = 12
2.9906975624424411 to the power of 4 equals 80.
4 times 21 equals 84.
Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.
x^(2)y^(2) + 2x^(3) y To factor 'x^(2) is common to both terms. Hence x^(2) [ y^(2) + 2xy] 'y' is common to both terms Hence x^(2)y[ y + 2x ] Fully factored.
The expression cannot be simplified.
The LCM of 2x5y and 4x3y2 is 4x5x3y2 = 60xy2.
since 648 = 2334 648 is divisible by any number that is 2x3y where x is between 0 and 3 and y is between 0 and 4. that gives you 20 possible answers.
2x^(3)y + 18xy - 10x^(2)y -90y Rearrange in ascending powers of 'x' . Hence 2x^(3)y - 10x^(2)y + 18xy -90y '2' & 'y' are common factor to all four terms. Hence 2y[ x^(3) - 5x^(2) + 9x - 45] Inside the 'square' brackets we factor the first two terms and the last two terms. Hence 2y[(x^(2){x - 5} + 9{x - 5}] To the two internal terms 'x - 5' is common. Hence 2y[x^(2) + 9)(x - 5)] Fully factored. NB 'x^(2) + 9 ' = x^(2) + 3^(2) does NOT factor . Remember two squared terms with a positive(+) between them does NOT factor. However, two squared terms with a negative(-) between them does factor.
4+4 equals 8.
And what is the question?

also 4
4-5 equals = -1
