Answer:

x = 35

Step-by-step explanation:

AE = AC = 4.1

∠ EAD = ∠ CAB = 92° ( vertical angles are congruent )

AD = AB = 2.9

Thus by the SAS postulate

Δ AED ≅ Δ ACB, thus

∠ AED and ∠ ACB are congruent

x = 35

5x−4y=34<br> −x+8y=22<br> elimination

Brut [27]

Answer:

The solution to the system of equations is:

$x=10,\:y=4$

Step-by-step explanation:

Given the system of equations

$\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}$

Multiply -x+8y=22 by 5: -5x+40y=110

$\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}$

so adding the equations

$-5x+40y=110$

$+$

$\underline{5x-4y=34}$

$36y=144$

solve 36y = 144 for y:

$36y=144$

divide both sides by 36

$\frac{36y}{36}=\frac{144}{36}$

Simplify

$y=4$

For 5x-4y=34 plug in y=4

$5x-4\cdot \:4=34$

$5x-16=34$

Add 16 to both sides

$5x-16+16=34+16$

Simplify

$5x=50$

Divide both sides by 5

$\frac{5x}{5}=\frac{50}{5}$

Simplify

$x=10$

Therefore, the solution to the system of equations is:

$x=10,\:y=4$

PLEASE HELP! WILL UPVOTE!

hram777 [196]

Standard form is
ax+by=c
where a and b and c are integers
and a is normally positivie

y+1/5=3x
minus 3x both sides
-3x+y+1/5=0
minus 1/5 both sides
-3x+y=-1/5
times -5 both sides
15x-5y=1
