Write two equations to model the growth of each tree, and set the equal to each other.
Let x equal the years.
For Type A, the equation is 3x+48 because the tree grows at 3 inches per year and, it started at 4 feet (48 in).
For Type B, the equation is x+72 because the tree grows at 1 inch per year, and it started at 6 feet (72 in).
3x+48=x+72
<em>*Isolate the variable by subtracting x from each side*</em>
2x+48=72
<em>*Subtract 48 from both sides*</em>
2x=24
<em>*Divide both sides by 2*</em>
x=12 years

Answer:
answer is 8
Step-by-step explanation:
2/3(x+7)=10
2x/3+14/3=10
2x/3=10-14/3==>30-14/3
2x/3=16/3
x=16/3*3/2
x=8
