The last one for sure all the wya
Answer:
T3 = 30
Step-by-step explanation:
9x + 3y - 6z = 18. 6. 3x-5y+10z= 15.
10x + 4y+5z = 20
Answer:
<em>reciprocal</em><em> </em><em>of</em><em> </em><em>3</em><em> </em><em>is</em><em> </em><em>1</em><em>/</em><em>3</em><em>.</em><em>.</em>
Given,
9(x+1) = 25 + x
expanding,
9x + 1 = 25 + x
bringing x to left hand side and taking 1 to right hand side with change in their respective signs,
9x - x = 25-1
=> 8x = 24
transposing 8 ,
=> x = 24/8 = 3
Hence x = 3
