Answer:
x = 1.5 ; y = -0.5
Step-by-step explanation:
2x + 4y = 1 ---------------------(i)
3x - 5y =7 ----------------------(ii)
(i) * 5 10x + 20y = 5
(ii)*4 <u> 12x -20y = 28 </u>
add, 22x = 33 { here y will be eliminated}
x = 33/22 = 3/2
x = 1.5
Put the value of x in equation (i)
2*1.5 + 4y = 1
3 + 4y = 1
4y = 1-3
4y = -2
y = -2/4 = -1/2
y = -0.5
Answer:
x=52
y=25
z=90
Step-by-step explanation:
x= 180-38-90=52
y= 180-(65+52)-38=25
z=180-65-25=90
