Look at this system of equations.

2x + 5 = 9.5

3x + 5y = 10.5

What is the value of x+y

x = 2.25 y = 0.75

Step-by-step explanation:

2x = 9.5 - 5

2x = 4.5

x = 4.5 : 2

x = 2.25

know we now what is x so in the second one we evaluate x

3 (2.25) + 5y = 10.5

6.75 + 5y = 10.5

5y = 10.5 - 6.75

5y = 3.75

y = 3.75 : 5

y = 0.75

that's it!

if you want to check your answer you can evaluate x and y so it will be like

2*2.25 + 5

= 4.5 + 5 = 9.5

and

3 * 2.25 + 5*0.75

= 6.75 + 3.75 = 10.5
