Answer:
x= 12
Step-by-step explanation:
distrubute the -2 to the 2x and -6
-4x+12= -3x
add 4x to both sides
12=x
Answer:
Step-by-step explanation:
you
60 +14*number of weeks
sister
120+10*number of weeks
let x be the number of weeks until they have the same amount of money
60+14x = 120+10x ; isolate like terms
14x -10x = 120-60
4x = 60; divide both sides by 4
x= 15 weeks
120+10*15 = 120+ 150 = $270 will be the amount they will have the same

First, distribute to simplify the equation.
-3*w = -3w
-3*4 = -12
-3w + (-12) = -18
Now, isolate the variable.
-3w + -12 = -18
+12 +12
- 18 + 12 --> -6
-3w = -6
-3w/-3 = -6/-3 >>>>> w = 2
Answer: w = 2
