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 <em><u>x </u></em><em><u>will </u></em><em><u>be </u></em><em><u>replaced </u></em>by a <em><u>the </u></em><em><u>first </u></em><em><u>equation</u></em>

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 <em><u>0</u></em><em><u>.</u></em><em><u>5</u></em> the value of x would be found by <em><u>taking </u></em><em><u>the </u></em><em><u>y </u></em><em><u>and </u></em><em><u>replacing</u></em><em><u> </u></em><em><u>it </u></em><em><u>with </u></em><em><u>0</u></em><em><u>.</u></em><em><u>5</u></em><em><u> </u></em><em><u>in </u></em><em><u>any </u></em><em><u>of </u></em><em><u>questions</u></em><em><u> </u></em><em><u>one </u></em><em><u>and </u></em><em><u>two.</u></em>

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 <em><u>y </u></em><em><u>is </u></em><em><u>0</u></em><em><u>.</u></em><em><u>5</u></em> and <em><u>x </u></em><em><u>is </u></em><em><u>0</u></em><em><u>.</u></em><em><u>7</u></em><em><u>5</u></em>

<em><u>0</u></em><em><u>.</u></em><em><u>5</u></em><em><u>*</u></em><em><u>0</u></em><em><u>.</u></em><em><u>7</u></em><em><u>5</u></em><em><u>=</u></em><em><u>0</u></em><em><u>.</u></em><em><u>3</u></em><em><u>7</u></em><em><u>5</u></em>

=0.375
