The sum of a variable and ten then decreased by three

• 10x/3

• (x+10) - 3

• x+10/3

-2(x+1) = 5

• Negative two multiplied by the sum of a variable and one is equal to five.

• Negative two times a variable plus one is five.

• Two multiplied by a variable increased by one is five.

Solve for X: 2x-3=-5x+25

• x=7

• x=4

• x=-4

• x=-7

|2x+1|=9

• x=4

• x=-5

• x=-5 and x=4

• x=10 and x=-8

Write an absolute value equation when the center is 8 and the distance is 2.

• |x-2| = 8

• |x+8| = 2

• |x-8| = 2

 $\frac{1}{3}\left(-2x+4\right)-4\left(-3x+\frac{1}{3}\right)$  

Distribute, answers are in terms decimals
