What is the ratio of x to y 4x 5y?
Assuming 4x = 5y Then x/y = 5/4
What are the soluition of these epautions 4x -5y -12 and -x 5y 18?
If you mean: 4x-5y = -12 and -x+5y =18 Then the solutions of the equations are: x = 2 and y = 4
What is 4x 3y -5x 2y?
The expression 4x - 3y - 5x - 2y can be simplified by combining like terms. Like terms have the same variables raised to the same powers. In this case, the x terms are like terms and the y terms are like terms. Combining the x terms, we get -x, and combining the y terms, we get -5y. Therefore, the simplified expression is -x - 5y.
What is 5y equals 4x-35 and slove for y?
5y = 4x - 35 Divide each side of the equation by 5 : y = 4/5 x - 7
Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
