Solving algebraically we get x=2 and y=-4

Step-by-step explanation:

We need to solve the equations:

y=-x-2\\y=-2x

Solving and finding value of x and y

Let:

y=-x-2\,\,eq(1)\\y=-2x\,\,eq(2)

Subtract both equations

y=-x-2\\y=-2x\\-\,\,\,\,+\\------\\0=x-2\\x=2

Putting value of x in eq(1) and find value of y:

y=-x-2\\y=-2-2\\y=-4

So, value of y is -4

Solving algebraically we get x=2 and y=-4

Solve for x: 12x +16y = 6
zubka84 [21]

Answer: x= 1/2- 4/3

At the bottom it says 0.5, so, 1/2= 0.5 and,

4/3= 1.33.....

Step-by-step explanation:

Add '-16y' to each side of the equation.

12x + 16y + -16y = 6 + -16y

Combine like terms: 16y + -16y = 0

12x + 0 = 6 + -16y

12x = 6 + -16y

Divide each side by '12'.

x = 0.5 + -1.3...y

Simplifying

x = 0.5 + -1.3...y
