Answer:
can you mark as expert
Step-by-step explanation:
5x-y=7 ......(1) equation 1
3x-2y=7.....(2)
5x - y = 7
3x - 2y = 7
by multiple equation one by 3 and two by 5
15x - 3y = 21
15x - 10y = 35
by subtracting equation one in two
-6y = 14
y = -14/6
y = -7/3
for value of x
let put the value of y into equation one
5x - (-7/3) = 7
5x + 7/3 = 7
5x = 7 - 7/3
5x = (21 - 7)/3
5x = 14/3
there fore the unknown values are required as
y = -7/3 and x = 14/3
