`2x+3y=8,4x+(3)/(2)y=7`

If ( 2x - 3y + 1)/(2) = (x + 4y + 8)/(3) = ( 4x - 7y + 2)/(5) then what is (x +y) equal to ?

If 2x+3y=34 and (x+y)/(y)=(13)/(8), then find the value of 5y+7x

On comparing the ratios (a_(1))/(a_(2)),(b_(1))/(b_(2)) and (c_(1))/(c_(2)), find out whether the following pair of linear equations are consistent,or inconsistent.(i) 3x+2y=5;2x-3y=7( ii) 2x-3y=8;4x-y=9 (iii) (3)/(2)x+(5)/(3)y=7;9x-10y=14( (iv) 5x-3y=11;-10x+6y=-22( v) (4)/(3)x+2y=8;2x+3y=12

Solve the simultaneous equations: 4x+ y/3=8/3, x/2 + (3y)/4 = -5/2

Sum of values of x and y satisfying 3^x-4^y=77, 3^(x/2)-2^y=7 is

x-2/3 y=8/3; (2x)/5-y=7/5

2x + 3y = 8 , x - 2y + 3 = 0

Solve : 2x+3y=7 3x-2y=8

2x+3y=8 4x-5y=-6

The of values of x and y satisfying 3^x -4^y=77 , 3^(x/2)-2^y=7
