Solve the system of equations above using it elimination write your answer in the form (x,y) 8X + Y = -16-3X + Y = -5
wlad13 [49]

Given the system of the equation below;

\begin{gathered} 8x+y=-16----(1) \\ -3x+y=-5----(2) \end{gathered}

We can use the elimination method to solve the systems of equations

Step 1: Subtract equation 2 from equation 1 and solve for x

\begin{gathered} 8x+y-(-3x+y)=-16-(-5) \\ 8x+y+3x-y=-16+5 \\ 11x=-11 \\ \frac{11x}{11}=-\frac{11}{11} \\ x=-1 \end{gathered}

Step 2: Sustitute x = 1 in equation 1

\begin{gathered} 8(-1)+y=-16 \\ -8+y=-16 \\ y=-16+8 \\ y=-8 \end{gathered}

Therefore, the solution to the system of equation is

(-1,-8)

Find the equation of the line that passes through A and B
Alex777 [14]

Answer:

First we need to find the slope. This is (7 - 3) / (4 - 2) = 2. Since we know the slope, we can use point-slope form. I'm using the point (2, 3).

y - 3 = 2(x - 2)

y - 3 = 2x - 4

y = 2x - 1

What is the value of x in the equation 3x-4y=65 when y =4
salantis [7]
3 x - 4 y = 65

Refine :

3 x - 4 * 4 =  65

3 x - 16 = 65

Add 16 to both sides :

3 x - 16 + 16 = 65 + 16

3 x = 81

Divide both sides by 3 :

3 x / 3  = 81 / 3

x = 81 / 3

x = 27

hope this helps!
