Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. X

Answer:

(15, 11).

Step-by-step explanation:

Given the system of equation;

X=2y-7 ..... 1

4x+y=71 ....2

Substitute 1 into2;

4(2y-7) + y = 71

8y - 28 + y = 71

9y - 28 = 71

9y = 71 + 28

9y = 99

y = 11

Substitute y = 11 into 1;

x = 2y - 7

x = 2(11)-7

x = 22-7

x = 15

hence the solution to the equation is (15, 11).

Please help me this question

Annette [7]

Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

$(y + 3) = - \frac{ 3}{4} (x - 8)$

Simplify it.

$(y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4}$

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...
