In the figure below, n II g. Find the values of y and r.
789
yo (3x – 27)

x = -7

Step-by-step explanation:

6-3*x-(27)=0

Step by step solution :

STEP

1

:

Pulling out like terms

1.1     Pull out like factors :

  -21 - 3x  =   -3 • (x + 7)

Equation at the end of step

Equations which are never true:

2.1      Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x+7 = 0

Subtract  7  from both sides of the equation :

                     x = -7

the answer is d. 75%
