A ^2+b^2=c^2 solve for c

musickatia [10]

Take the root of both sides, and then solve.
c = sqrt a^2 + b^2, - sqrt a^2 + b^2.

System of equations <br> 3x-2y=8<br> -2x+5y=-9<br> x=<br> y=

natka813 [3]

Answer:

2y = 3x - 8

y = 3/2x - 4

Work

-2x + 5(3/2x - 4) = -9

-2x + 15/2x - 20 (+20) = -9 (+20)

-4/2x + 15/2x = 11

11/2x * (2/11) = 11 (2/11)

x = 2

3(2) - 2y = 8

6 (-6) - 2y = 8 (-6)

-2y = 2

y = - 1

final answer:

x = 2

y = -1
