Answer:
x = 4
Step-by-step explanation:
9(x - 2) = 18
9x - 18 = 18
9x = 18 + 18
9x = 36
x = 36/9
x = 4

Answer:
2. is x = -3
Step-by-step explanation:
-3( x - 3) = 12
multiply the things in the () by -3
-3x+9=12
subtract 9 from both sides
-3x+9-9=12-9
-3x=3
divide both sides of the equation by -3
x = -3
2x+4= 3x-6+2
2x+4=3x-4
2x-3x+4=3x-3x-4
-x+4=-4
-x+4-4= -4-4
-x=-8
Need to multiply by -1 for x to be positive and also for -8
-1(-x)= -1(-8)
x=8
