Answer:
0.375
Step-by-step explanation:
1.y=2x-1
2.y=-x+2
using substitution method
1.y=2x-1
y+1=2x
the other equation where there is an x will be replaced by a the first equation
so
2.y=-(y+1)+2
y=-y-1+2
y=-y+1
y+y=1
2y=1
2y/2=1/2
y=0.5
the value of y is 0.5 the value of x would be found by taking the y and replacing it with 0.5 in any of questions one and two.
1.y(0.5)=2x-1
0.5=2x-1
0.5+1=2x
1.5=2x
1.5/2=2x/2
0.75=x
the value of y is 0.5 and x is 0.75
0.5*0.75=0.375
=0.375
