Answer:
Variant c
Step-by-step explanation:
c²=4*9
c=6
You can apply phyphagor
b²=6²+9²=36+81=117

Add 3b to both sides and divide by a to isolate x.
ax - 3b = c
ax = c + 3b
x = c +3b / a
Hope This Helps You!
Good Luck Studying :)
Solve for x
3x=4y-10
x=(4y-10)/3
solver for y
3x=4y-10
rewrite as 4y-10=3x
4y-10+10=3x+10
4y=3x+10
y=(3x+10)/4
