Answer: x = 0 and x = 1

Explanation:

The image of the graph is in the figure attached.

There you can observe two intersection points which are (0,2) and (1,3), therefore the solutions are x = 0 and x = 1.

You can draw the graph by constructing a table with x from - 2 to 4, like this:

x             f(x) = x + 2            g(x) = 2^x + 1

-2             -2 + 2 = 0             2^2 + 1 = 4 + 1 = 5

- 1            -1 + 2 = 1             2^1 + 1 = 2 + 1 = 3

0                0 + 2 = 2             2^0 + 1 = 1 + 1 = 2  => this is one solution

1                1+ 2 = 3              2^1 + 1 = 2 + 1 = 3 => this is the other solution

2                2 + 2 = 4             2^2 + 1 = 4 + 1 = 5

_______________________________

<h3>I'm solving it using substitution method:-</h3>

<h3>7x+2y=3 {given}</h3>

<h3>=>7x=3-2y</h3>

<h3>=>x=(3-2y)/7-------(1)</h3>

<h3>x-3y=30 {given}</h3>

<h3>=>x=30+3y</h3>

<h3>=>(3-2y)/7=30+3y {putting the value of x from eqn 1}</h3>

<h3>=>3-2y=210+21y</h3>

<h3>=>3-210=21y+2y</h3>

<h3>=>-207=23y</h3>

<h3>=>y= -207/23= -9</h3>

<h3>putting the value of y on eqn(1):-</h3>

<h3>x=(3-2y)/7</h3>

<h3>x=>(3-2(-9))/7=(3+18)/7=21/7=3</h3>

<h2>Hence, x=3, y= -9</h2>
