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

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
