Answer:
N + 3 = -5
n= -8
N-4=9
n=13
4+N=10
n=6
-10+N=3
n=13
N-10=1
n=11
-11+n=-12
n=-1
N+19=20
n=1
15+N=-10
n=-25
N-6=-12
n=-6
N+4=16
n=12
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
An equilateral triangle has 3 equal sides.
So
4(x-1) = x +8
4x-4=x+8
3x=12
x=4
Same result obtained when comparing the other pairs of equations.
