H=henry's age
j=justin's age
h=10j
in 6 years (h+6 and j+6)
h+6=4(j+6)
the equations are
h=10j and
h+6=4(j+6)
C is answer
Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5
