6x+8y=20 4x-6y=12 please​

Answer»

Answer:

6x+8y=20

simplifying

6x + -8y = 20 Solving 6x + -8y = 20 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8y' to each side of the equation. 6x + -8y + 8y = 20 + 8y COMBINE like terms: -8y + 8y = 0 6x + 0 = 20 + 8y 6x = 20 + 8y Divide each side by '6'. x = 3.333333333 + 1.333333333y Simplifying x = 3.333333333 + 1.333333333y

4x-6y=12

First, SUBTRACT 6y from each side of the equation to ISOLATE the x term while keeping the equation balanced:

4x+6y−6y=12−6y

4x+0=12−6y

4x=12−6y

Now, divide each side by 4 to solve for x while keeping the equation balanced:

4x4=12−6y4

4x4=12−6y4

x=12−6y4

Or

x=124−64y

x=3−2×32×2y

x=3−2×32×2y

x=3−32y
