Answer: x=1/2=0.5
Step-by-step explanation:
Given
3(2x) - 4(3x) + 3= 0
Expand parenthesis
6x - 12x + 3 = 0
Combine like terms
-6x + 3 = 0
Subtract 3 on both sides
-6x + 3 - 3 = 0 - 3
-6x = -3
Divide -6 on both sides
-6x / -6 = -3 / -6
x = 1/2 = 0.5
Hope this helps!! :)

Answer:
128
Step-by-step explanation:
Answer:
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
Step-by-step explanation:
Let
x ---->Joe's age
y ----> Aaron's age
z----> Christina's age
we know that
Joe"s Age Is three times Aaron's age
----> equation A
Aaron is six years older than Christina
isolate the variable z
----> equation B
The sum of their ages is 149
----> equation C
solve the system by substitution
substitute equation A and equation B in equation C
solve for y
Combine like terms left side
Adds 6 both sides
Divide by 5 both sides
<em>Find the value of x</em>
---->
<em>Find the value of z</em>
----
therefore
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
