Answer:
22
Step-by-step explanation:
it is epuivalet
X= -1 t= 7
4(3x-1)=3+8x-11
12x-4=3+8x-11
12x-8x=4+3-11
4x= -4
\4. \4
x= -1
2t+4+5t=6t+11
2t-6t+5t=-4+11
1t=7
\1. \1
t=7
Answer:
2
Step-by-step explanation:
15+12=27
54 / 27 = 2
One decade is 10 years+ 8 years is 18 total years
18 minus 9 is 9 years
Hope this helps
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
