Answer:
x=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−x=2−3x+6
Step 1: Simplify both sides of the equation.
−x=2−3x+6
−x=2+−3x+6
−x=(−3x)+(2+6)(Combine Like Terms)
−x=−3x+8
−x=−3x+8
Step 2: Add 3x to both sides.
−x+3x=−3x+8+3x
2x=8
Step 3: Divide both sides by 2.
2x/2 = 8/2
x=4
Answer:
1. x = 1 over 2 or you can simplify by writing x = 0.5
2.x = -1 over 3 or x= -0.3
3.x = -17
4.x = 9
5.x = 7
6.-4 over 9 or x = -0.4
7.x = 1 over 10 or x = 0.1
8.x = 1 over 4 or x = 0.25
9.x = -1
10.x = 13
