Answer:
Value for x variables is x = 0.2
Step-by-step explanation:
We have the equation
3.5 + 1.2 (6.3 - 7x) = 9.38
We need to isolate the unknown value X.
First step is to multiply 1.2 and break the parenthesis.
3.5 + 7.56 - 8.4x = 9.38.
After that we can join together values with x and values without variables.
If we need to move a term from left to right side or the opposite, we need to change to the opposite sign. For example -8.4x will cross to the other side as 8.4 x
3.5 + 7.56 - 9.38 = 8.4 x
After that we can combine the terms with the sum.
1. 68 = 8.4 x
Then, 8.4 is multiply the x. It can go to the other side dividing.
1.68/8.4 = 8.4x / 8.4
0.2 = x
Finally x value is 0.2 x = 0.2.
