Question

0.8x+2.71=1.898-0.6x Solve for x

Answer 1

0.8x + 2.71 = 1.898 - 0.6x  
Add 0.6x to each side.  
0.6x + 0.8x + 2.71 = 1.898 - 0.6x + 0.6x
1.4x + 2.71 = 1.898
Subtract 2.71 from both sides.  
-2.71 + 1.4x + 2.71 = 1.898 - 2.71
1.4x = -0.812
____=_____
1.4    =   1.4
Divide by 1.4

x = -0.58

Answer 2

0.8x + 2.71 = 1.898- 0.6x
To solve this, first isolate x on 1 side of the equation.
To do this, add 0.6x to both sides.
1.4x + 2.71 = 1.898

Now, subtract 2.71 from both sides.
1.898 - 2.71 = -0.812
1.4x = -0.812

Last, divide both sides by 1.4.
-0.812 / 1.4 = -0.58
x = -0.58

Answer:
x = -0.58
