Question

Which system of equations has a solution of approximately (0. 6, –0. 8)?

x + 2 y = negative 1 and 3 x + y = 1

x minus 2 y = 1 and 3 x + y = 1

x minus 2 y = 1 and 3 x minus y = negative 1

x + 2 y = negative 1 and 3 x minus y = negative 1

Answer 1

The system of equation x+2y=-1 and 3x+y=1 will have the solution (0.6,0.8).

What is system of equation?

System of equations, often known as simultaneous equations, Two or more equations to be solved together in algebra (i.e., the solution must satisfy all the equations in the system). The number of equations must equal the number of unknowns for a system to have a unique solution. A system of equations is a collection of two or more equations that have the same variables. A solution to a system of equations is a set of variable values that satisfy all of the equations at the same time.

Here,

given point,

(x,y)=(0.6,-0.8)

given equations,

x+2y=-1 and 3x+y=1

x-2y=1 and 3x+y=1

x-2y=1 and 3x-y=-1

x+2y=-1 and 3x-y=-1

for first equation,

=0.6+2*-0.8

0.6-1.6=-1

3*0.6-0.8

1.8-0.8=1

The solution to the system of equations x+2y=-1 and 3x+y=1 will be found (0.6,0.8).
