Answer:
BH = 2
Step-by-step explanation:
The altitude divides the triangle into similar triangles. The ratio of the long side to the short side is the same for all, so ...
AH/BH = BH/HC
4/BH = BH/1
4 = BH² . . . . multiply by BH
2 = BH . . . . . take the square root
-26= -9x + 10
-26 - 10= -9x
-36=-9x
-36:(-9)=x
4=x
1. you pass +10 to the left in minus
2. you resolve what you've got on the left
then you pass the multiplying -9 to the left dividing
