Solve the system of equations using elimination

I know it is going to be a really long answer but here is the

Simplifying 6x + 8y + -6z = 62 Solving 6x + 8y + -6z = 62 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 + -6z = 62 + -8y Combine like terms: 8y + -8y = 0 6x + 0 + -6z = 62 + -8y 6x + -6z = 62 + -8y Add '6z' to each side of the equation. 6x + -6z + 6z = 62 + -8y + 6z Combine like terms: -6z + 6z = 0 6x + 0 = 62 + -8y + 6z 6x = 62 + -8y + 6z Divide each side by '6'. x = 10.33333333 + -1.333333333y + z Simplifying x = 10.33333333 + -1.333333333y + z

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
