Answer:
x=1
Step-by-step explanation:
7x - 20 = 2x - 3(3x + 2)
Distribute
7x -20 = 2x -9x -6
Combine like terms
7x-20 =-7x -6
Add 7x to each side
7x+7x-20 =-7x+7x -6
14x -20 = -6
Add 20 to each side
14x-20+20 =-6+20
14x = 14
Divide by 14
14x/14=14/14
x=1
In dividing two equation with variables and exponent, First you must align or rearrange the equation and group them base on their variables but don't forget the sign of each variables. Second, proceed in dividing its quantity and then subtract its exponent to the other variables having the same. So by calculating it, the answer would be X or X^1
Distribute.
-2(8)=-16
-16+7=-9
The answer is -9
-3 would be before the zero and the point would be on the 3.3 on the line
