Question

solve using substititution method for 2x-3y=1.3 and y- x=0.5

Answer 1

Answer:

x=-2.8

y=-2.3

Step-by-step explanation:

given,

2x-3y = 1.3

y-x=0.5

from this

y=0.5+x ---------1

and substitute the value of y to

2x-3y = 1.3

then,

2x-3(0.5+x)=1.3

2x-1.5-3x=1.3

-x=1.3+1.5

-x=2.8

x=-2.8

and put the value of x in equation 1

y-(-2.8)=0.5

y+2.8=0.5

y=0.5-2.8

y=-2.3
