Question

solue
for x and
y using
substitution method
1)3x-4y-1= 0, 2x-8y/3=-5
11) 4x-y-10 = 0, 2x- 1y/2= 5​

Answer 1

Answer:

1) 3x-4y-1=0

2x-8y/3=-5

2x=8y/3-5

x=8y-15/6

substitute x in the above equation

3(8y-15/6)-4y-1=0

16y-15-8y-2=0

8y-17=0

y=17/8

3x-17/2-1=0

6x-17-2=0

6x=19

x=19/6
