-2x+3y=-18
Y+6=18÷2
U can subtract 18 from each side of the equation.
How do you solve y=-4x+1
What are the mathemtical signs????? Is it y^2 + 7y - 18 This factors to ( y - 2)(y + 9) or y^2 - 7y - 18 (y + 2)(y - 9)
48
Total solution depends on the value of y. -18y-18 or -18(y+1)
As written, that's 17y + 4 which is in its simplest form. -6y^2 + 23y + 4 factors to (4 - y)(1 + 6y)
You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
y2+7y=18 y2+7y-18=0 (y+9)(y-2)=0 y=-9 & y=2
Y+6=18÷2
That's not an equation, it is not solveable.
To solve the system of equations given by ( x + 7y = 39 ) and ( 3x - 2y = 2 ) using substitution, we can first solve the first equation for ( x ): ( x = 39 - 7y ). Substituting this into the second equation gives ( 3(39 - 7y) - 2y = 2 ). Simplifying this results in ( 117 - 21y - 2y = 2 ), or ( 117 - 23y = 2 ), leading to ( 23y = 115 ) and ( y = 5 ). Plugging ( y = 5 ) back into ( x = 39 - 7(5) ) gives ( x = 4 ). Thus, the solution in ordered pair form is ( (4, 5) ).
y + y + 2 = 182y + 2 = 182y = 16y = 8whew !
U can subtract 18 from each side of the equation.
6x +108=18y y=6x/18+108/18 y=x/3+6
In this type of problem let the numerator of a fraction be 23.29 and its denominator be twice the coefficient of the variables and so:- 29*(23.29/58)+23*(23.29/46) = 23.29 Therefore the possible values of x and y are 23.29/58 and 23.29/46 respectively
18+y=32 y=14
