−10y+9x=−9 10y+5x=−5 ​

Mathematics
1 answer:
frozen [14]3 years ago
6 0

Answer:

x = - 1 ;  y =0

Step-by-step explanation:

     −10y+9x= −9    --------------> EQU 1

       10y+5x= −5 ​    --------------> EQU 2

____________________

       0 + 14x = -14                     { add EQU 1 and EQU 2 }

                  x = -14/14

                   x = -1

Substitute the value of x in EQU 1;

-10y + 9 *(-1) = -9

-10y - 9  = -9

        -10y = -9 +9 = 0

             y = 0

What are the roots of this equation 2x^2+7x-3=0
Ludmilka [50]

Step-by-step explanation:

2x^2+7x-3=0

by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>

Let's solve your equation step-by-step.

2x2+7x−3=0

For this equation: a=2, b=7, c=-3

2x2+7x+−3=0

Step 1: Use quadratic formula with a=2, b=7, c=-3.

x=

−b±√b2−4ac

2a

x=

−(7)±√(7)2−4(2)(−3)

2(2)

x= −7±√73 /4

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73

Answer:

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73
