"Y over 39" ... usually written as y/39 ... is neither a question nor a problem,
and needs no answer or solution. It's nothing but a number, which you can
identify immediately, as soon as you know the numerical value of 'y'.

Divide both numbers by their greatest common factor, 3.
-9x + y = 39 y = 9x + 39 The y-intercept is where x = 0 Therefore the y intercept is where: y - 9(0) = 39 y = 39 The y intercept is 39 The x-intercept is where y = 0 Therefore the y intercepet is where: 0 - 9x = 39 - 9x = 39 9x = - 39 x = -39/9
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) ).
How do you solve y=-4x+1
The answer is '39 Inches in a Metre'.
solve x=yz for the variable y
A1: 7x-4y=9 , 3x+2y=15 and 7x-4y=9, 6x+4y=30 so 13x=39 x=3 now plug it in for y 9+2y=15 so y=3 A2: The right expression is missing a + or - between the 3x and 2y. For the purpose of this demo, let's assume it is 3x+2y-15. It can be solved by multiplying the right expression by 2, then add the expressions. That will eliminate y. Then solve for x. When x is known, plug its value into either of the expressions and solve for y. To start: 2(3x+2y-15)=6x+4y-30 adding the two (7x-4y-9)+(6x+4y-30)=13x+0y-39=13x-39 solve for x
Solve for y: f(-5)=13+2x
x + 7y = 39 So x = 39 - 7y Substitute for x in the second equation: 3(39 - 7y) - 2y = 2 117 - 21y - 2y = 2 115 = 23y y = 5 Substitute this value for y back into the first equation: x + 7*5 = 39 x + 35 = 39 x = 4
-y + y equals 0.
