Y=x+3 y=2x+5 System of equations using Substitution

(-2,1)

Step-by-step explanation:

y=x+3  

y=2x+5  substitute  the y value in the first equation into the second equation

x+3 = 2x+5  now solve for x

   -3        -3

x = 2x +2   subtract 2x from both sides

-2x   -2x

-1x = 2       Divide both sides by -1

x= -2  

The value of x is -2 to plot it into one of the equations to solve for y.

y= -2 + 3

y = 1  

(-2,1)

im assuming you want an equation for this. if so it would be 3x+15
