How do you factorise y squared minus 10y plus 16?
(y - 8)(y - 2)
What is 10y-4y?
10y-4y = 6
What does y stand for in 15y plus 14 equals 2 times 5y plus 6?
15y+14=2(5y+6) 15y+14=10y+12 15y+14-14=10y+12-14 15y=10y-2 15y-10y=10y-2-10y 5y=-2 y=-2/5
If 10y-6 is equal to 2 plus 4y what does y equal?
you have to bring the "y" to one side. 10y - 6 = 2 + 4y 10y-4y = 2 + 6 6y = 8 y = 8/6 If you substitute 8/6 into y you will find that 8/6 is the answer
If x 3 and y 2 then 3x 10y?
The answer is: x-y = 11 3x+10y = -6
10y-3=4y+6?
10y-3=4y+6 10y = 4y + 9 6y = 9 y = 9/6 y = 3/2 y = 1.5
Solve the equation10y equals 6y plus 5 plus 3y?
10y= 6y+5+3y 10y=6+9y y=6
-6 - 10y equals - 10?
-6 - 10y = -10 Add 6 to both sides: -10y = -4 Divide both sides by -4: y = -4/-10 = 4/10 = 0.4 Check by putting the value back into the equation: -6 - (10 x 0.4) = -6 -4 = -10
How do you factorise 6t 12s?
6(t2s)
How do you solve the system of equation problem in algebra 8x-10y equals 2 added with 7x-5y equals 13?
8x - 10y = 27x - 5y = 13First, we need to eliminate one of the variables. For this, we would like to have them with the same coefficient but different sign. We can do this if we multiply by -2 the second equation.8x - 10y = 2-2(7x - 5y) = -2(13)8x - 10y = 2-14x +10y = -26Now, we can add both equations, and solve for x.(8x - 10y) + (-14x + 10y) = (2) + (-26)(8x - 14x) +(-10y + 10y) = (2 - 26)-6x = - 24-6x/-6 = - 24/-6x = 4Substitute 4 for x in the first equation:8x - 10y = 28(4) - 10y = 232 - 10y = 232 - 32 - 10y = 2 - 32-10y = -30-10y/-10 = -30/-10y = 3Thus, the solution of the system is (4, 3).Check:
Is x equals 6 and y equals 8 then 9x plus 10y equals?
x = 6y = 89x + 10y = 9(6) + 10(8) = 54 + 80 = 134
How do you factorise x squared - 5x - 6?
(x - 6)(x + 1)
