Answer:
x = 5
Step-by-step explanation:
Start by distributing the 5 to remove parentheses. To do this multiply the numbers and variable in the parentheses by 5.
10x - 20 - 11 = 4 + 3x
Next. you want to get the variables to one side. This is done by subtracting 3x from both sides.
7x - 20 - 11 = 4
Now solve the -20 - 11.
7x - 31 = 4
You need to have the variable all by itself. To do this, first add -31 to both sides.
7x = 35
Finally divide by 7.
x = 5
