Question

3X+[-1 -2] = [-13 -2]
10 -7 -5 14

Answer 1

x= −668/3

Explanation:

Step 1: Simplify both sides of the equation.

3x−1−2=(−13−2)(10)−7−514

3x+−1+−2=−150+−7+−514

(3x)+(−1+−2)=(−150+−7+−514)(Combine Like Terms)

3x+−3=−671

3x−3=−671

Step 2: Add 3 to both sides.

3x−3+3=−671+3

3x=−668

Step 3: Divide both sides by 3.
