x-1\geq 30+3x
Use the distributive property to multiply 3 by 10+x.
x-1-3x\geq 30
Subtract 3x from both sides.
-2x-1\geq 30
Combine x and -3x to get -2x.
-2x\geq 30+1
Add 1 to both sides.
-2x\geq 31
Add 30 and 1 to get 31.
x\leq -\frac{31}{2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
