3(x + 2) = 2x + 5 justification/ reason

x = -1

Step-by-step explanation:

3(x + 2) = 2x + 5

Use the distributive property on the left side.

3x + 6 = 2x + 5

Subtract 2x from both sides. Subtraction property of equality.

x + 6 = 5

Subtract 6 from both sides. Subtraction property of equality.

x = -1

Step-by-step explanation: 3(x+2)=2x+5

                                               3x+6=2x+5

                                                -3x   -3x

                                                    6=1x+5

                                                     -5     -5

                                                       1=1x

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
