Answer:
x=6.7
Step-by-step explanation:
To solve this problem is necessary to perform basic operations in order to reduce the amount of work.
This means that we need to sum coefficients of 'x' in boths side of equations, and do the same thing to free terms.
Therefore, The expression 0.3+1.4(x+1)=4.4x+8.3-3x, becomes
0.3+1.4(x+1)=4.4x+8.3-3x
1.4x+1.7=1.1x+8.3
Next
Lets isolate x variable in one side of equality sign
1.4x+1.1x=8.3+1.7
1.5x=10
x=10/1.5
