Expanding the left side of the equation:
0.9 -3 2x - 0.9 -3 (-1) = 2.8 - 3.19x-2.7x + 2.7 = 2.8 - 3.19x
Combine like terms:
2.7 = 2.8 - 3.19x + 2.7x2.7 = 2.8 - 0.49x
Now, isolate x:
2.7 - 2.8 = -0.49x-0.1 = -0.49xx = -0.1 / -0.49x = 0.2041
Therefore, the value of x is 0.2041.
Expanding the left side of the equation:
0.9 -3 2x - 0.9 -3 (-1) = 2.8 - 3.19x
-2.7x + 2.7 = 2.8 - 3.19x
Combine like terms:
2.7 = 2.8 - 3.19x + 2.7x
2.7 = 2.8 - 0.49x
Now, isolate x:
2.7 - 2.8 = -0.49x
-0.1 = -0.49x
x = -0.1 / -0.49
x = 0.2041
Therefore, the value of x is 0.2041.
