Question
Solve the equation
x=−31
Alternative Form
x=−0.3˙
Evaluate
(x−3)×2=(x×10)×2
Remove the parentheses
(x−3)×2=x×10×2
Simplify
x−3=x×10
Use the commutative property to reorder the terms
x−3=10x
Move the variable to the left side
x−3−10x=0
Subtract the terms
More Steps

Evaluate
x−10x
Collect like terms by calculating the sum or difference of their coefficients
(1−10)x
Subtract the numbers
−9x
−9x−3=0
Move the constant to the right side
−9x=0+3
Removing 0 doesn't change the value,so remove it from the expression
−9x=3
Change the signs on both sides of the equation
9x=−3
Divide both sides
99x=9−3
Divide the numbers
x=9−3

Evaluate
2(x−3)
Apply the distributive property
2x−2×3
Multiply the numbers
2x−6
2x−6=20x
Move the variable to the left side
−18x−6=0
Move the constant to the right side
−18x=6
Multiply both sides
18x=−6
