x=1/5
Step-by-step explanation:
5x-3 (5x+10) - 14=82-128
Simplify the right side; 82-128=-46
5x-3 (5x+10) - 14=-46
Add 14 to both side to rid the variable side from the constant.
5x-3 (5x+10) = -32
Distribute the - 3 over to the parenthesis.
5x-15x-30=-32
Combine like terms
-10x-30=-32
Add 30 to both sides to rid the variable of the constant.
-10x=-2
Divide both sides of the equation by - 10 to isolate the variable
You are left with x=1/5

x = 1/5
Step-by-step explanation:
Given
5x-3 (5x+10) - 14 = 82 - 128
Using the distributive property we have
5x - 3x5x + - 3x10 - 14 = 82-128
5x - 15x - 30 - 14 = - 46
-10x - 44 = - 46
Add 44 to both sides
-10x - 44+44 = - 46 + 44
-10x = - 2
Now divide both sides by - 10 to get the unknown x
-10x/-10 = - 2/-10
x = 1/5
