12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x

Answer:
A Rs. 500 note, and four Rs. 100 notes.
Step-by-step explanation:
The cost of the two shoes = Rs.1,300 + Rs. 1,800
= Rs. 3,100
He gave 4 notes of Rs. 1,000 = 4 x Rs. 1,000
= Rs. 4,000
Manoj's expected change = Rs. 4,000 - Rs. 3,100
= Rs. 900
Since he was returned 5 notes in the denominations of Rs. 500 and Rs. 100, then;
Rs. 500 + Rs. 100 + Rs. 100 + Rs. 100 + Rs. 100 = Rs. 900
Therefore, Manaoj was returned a Rs. 500 note, and four Rs. 100 notes.
215° because when you add multiples of 360 until you get an angle in the desired range.
Answer:
-4x+ 1/10
Step-by-step explanation:
−1/2x−1/5−5x+3/10+3/2x
Combine like terms
-1/2x -5x + 3/2x -1/5 + 3/10
Get a common denominator for each group
-1/2x -10/2x + 3/2x -2/10 + 3/10
-8x/2 + 1/10
Simplify
-4x + 1/10
-4x + 1/10
