2x+2y=38
y=x+3

First you would substitute the y for x+3
2x+2(x+3)=38

You would multiply the 2 by the x+3
2x+2x+6=38

Add the 2x and the 2x
4x+6=38

Subtract the 6 on both sides
4x=32

Divide the 4 on both sides
x=8

Now substitute the x in the second problum for 8
y=8+3

Add the 8 and the 3 to solve for y
y=11

Your answers
x=8
y=11
the correct answer would be A:(8,11)

What is the domain and range and function ??? Then can u explain how u did it please and thank you
enot [183]
The domain is
- 10 \leqslant x \leqslant 10
and the range is
- 5 \leqslant y \leqslant 5
Domain is x values (horizontal axis), while range is y values (vertical axis). On a line like this one, domain is calculated from the left most point to the right most, while range is calculated from the down most to the upmost.
Because this line is a solid line rather than a dotted line, less than or equal to
\leqslant
signs are used rather than just
<
less than signs.

3x+y=1/3<br> 2x-3y=8/3<br><br> Solve the system of linear equation using any method.
krek1111 [17]
3x + 1y = ¹/₃   ⇒ 9x + 3y = 1
2x -  3y = 2²/₃ ⇒ 2x -  3y = 2²/₃
                                 11x = 3²/₃
                                  11     11
                                     x = ¹/₃
                             3x + y = ¹/₃
                         3(¹/₃) + y = ¹/₃
                               1 + y = ¹/₃
                             - 1        - 1
                                     y = ⁻²/₃
                              (x, y) = (¹/₃, ⁻²/₃)
