solve for X + 60 is equal to 15 and 3 x minus 4 Y is equal to 7 and find the value of k if Y is equal to x minus 2 now to get the value of a minute to get the value of Y and X from this equation now to simplify this equation we just need to put one device is equal to M and similarly in this case also this will simplify the occasion let se 1 by Y is equal to I am therefore this question will be 4 x + 6 m is equal to 15 and this equation will be 3 x minus 4 is equal to 7 mausi to get expovision same we just need to multiply this

week by 3 and this equation back for so let's do that lets say this equation 1 and this is our equation to multiply question 1 by 3 we get 12 x + 18 is equal to 45 45 and this equation will be 12 - 16 is equal to 7 into 4 is 28 now subtract this is this equation from this equation we get that said this is minus b will be plus it will be - now we get city name + 16 which is equal to 34 sorry 34 is equal to

45 / 20 - 28 is equal to 70 therefore M will be equal to 1 by 2 I will be equal to 1 by 2 is equal to 1 by 2 we will get X just put a musical 202 in this equation we will get x is equal to 4 x + 16 to 1 by 2 is 3 is equal to 15 is equal to 15 therefore if x is equal to 15 - 3 which is 12 / 4 which is equal to 3 x is equal to 3 now we have access equal to 3 and x is equal to 1 by 2 if m is equal to 1 by 2 why will be equal to Y will be equal to 2 and x is equal to 3 now we have X and Y so we can go for a now it is given that Y is equal to x minus

Ghar 4 Y is equal to 22 is equal to a n to Excess 3 - 2 this is given from this we can write 2 is equal to 3 minus 2 which is which will give us a is equal to 4 by 3 therefore a is equal to 4 battery saver final answer this is the value of a
