Answer:
-3(x+2)-7 = 5x + 7
-3x - 6 - 7 = 5x + 7
-3x - 13 = 5x + 7
-20 = 8x
x = -2.5
Answer:
Exact form = x=-5/2
Decimal form = x=-2.5
Mixed number form = x=-2 1/2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
-3(x+2)-7 = 5x + 7
-3x - 6 - 7 = 5x + 7
-3x - 13 = 5x + 7
-20 = 8x
Divide both sides by 8 to get x by itself

Answer:
Step-by-step explanation:
x-4=0
x=4
p(x)=cx^3-15x-68=0
p(x)=c(4)^3-15(4)-68=0
p(x)=64c-60+68=0
p(x)=64c+8=0
p(x)=64c=-8
p(x)=c=-8/64
p(x)=c=-1/8
