9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
12y+3=9y-15 3y=-18 y=-6
36x-9y = 15 -9y = -36x+15 y = 4x-5/3 in slope intercept form
If you mean: -3x+9y = -6 then it is y = 1/3x-2/3
15xplus 3
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
its 10x +9y +1z
9y-3 = 6
This is simply a set of algebraic expressions which has no simpler form. Perhaps there should be an equals sign somewhere.
9y+3 = 5y+13 9y-5y = 13-3 4y = 10 y =2.5
The GCF is 15x.
5x + 9y-3 is a trinomial term true of false
5x - 9y = 43 (A)3x + 8y = 68 (B)(A)*3: 15x - 27y = 129(B)*5: 15x + 40y = 340Subtracting the first from the second gives67y = 211 => y = 211/67 = 3.15 approxSubstituting the [rational] value of y in (B)5x - 9*211/67 = 43 => 5x = 43 + 1899/67 = 4780/67therefore x = 956/67 = 14.27 approx.
12y+3=9y-15 3y=-18 y=-6
y = 3 in the equation 31 = 4 - 9y Solve for y. 31 - 4 = 4 - 9y - 4 Simplify 27 = 9y Divide both sides by 9 to get the term y by itself on one side of the equation. 27 / 9 = 9y / 9 Simplify 3 = y
36x-9y = 15 -9y = -36x+15 y = 4x-5/3 in slope intercept form
-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3
