equal height is 72 inches
Step-by-step explanation:
initial height of tree one = 36inches
initial height of tree two = 48inches
36 + 15x = 48 + 10x

x = -2
Step-by-step explanation:
2(x - 5) - 5x = -4
Distrubute the 2 into the parentheses
2x - 10 - 5x = -4
Add 10
+10 +10
2x - 5x = 6
Simplify
-3x = 6
Divide
÷ -3 ÷ -3
x = -2
