Question

solve -x+6=x-8

Answer 1

x=7. -7+6=1 and 7-8=1

Answer 2

Bring the x to the other side but substracting it
-x - x + 6 = -8
Add like Terms :
-2x + 6 = -8
Substract 6 to bring to the other side
-2x = -6 + -8
-2x = -14
Divide by -2 on both sides
x = 7

Answer 3

get your like terms together
-x+6=x-8
add 8 on both sides
-x+6+8=x
add x on both sides
-x+x+6+8=x+x
0+14=2x
2x=14
x=7
