In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top equation by 5. Now multiply the bottom equation by −3. Next add the equations, and solve for y.

Answer:

<em>In </em><em>the </em><em>above</em><em> </em><em>figure</em>

<em>both </em><em>the </em><em>sides </em><em>are </em><em>equal</em><em> </em><em>then</em><em> </em><em>angle </em><em>between</em><em> </em><em>them </em><em>will </em><em>also </em><em>equal</em>

<em>so,</em>

<em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>3</em><em>x</em><em>+</em><em>1</em><em>)</em><em> </em><em>=</em><em> </em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>7</em><em>5</em><em> </em>

<em>x </em><em>=</em><em> </em><em> </em><em>1</em><em>7</em><em>5</em><em>/</em><em>7</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>5</em>

hence angle will (25 *2) +2 =52

other angle is( 25*3)+1 = 76

<em>hope </em><em>it </em><em>helps</em><em> </em><em>and </em><em>your </em><em>day </em><em>will </em><em>fine</em>

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)


To find the slope, you can use the slope formula and plug in the two points:

(3,63) = (x₁ , y₁)

(5,107) = (x₂, y₂)

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{107-63}{5-3}

m=\frac{44}{2}

m = 22


Now that you know m = 22, plug it into the equation:

y = mx + b

y = 22x + b

To find "b", plug in one of the points into the equation (I will do both points)

(3,63)

y = 22x + b

63 = 22(3) + b

63 = 66 + b    Subtract 66 on both sides

-3 = b


(5,107)

y = 22x + b

107 = 22(5) + b

107 = 110 + b    Subtract 110 on both sides

-3 = b


y = 22x - 3
