Answer:

v= 13

w= -32

Step-by-step explanation:

2v+6w=-36

5v+2w=1

2w= 1-5v

2v+ (3)(1-5v)= -36

2v+3-15v= -36

3-13v =-36

3--36= 13v

39= 13v

13 = V

5×13+2w=1

65+2w=1

1-65= 2w

-64=2w

-32=w

Find the value of x that make it true

lesantik [10]

Answer:

Step-by-step explanation:

1). 10 = $\frac{1+7x}{7+x}$

10(7 + x) = 1 + 7x

70 + 10x = 7x + 1

10x - 7x = 1 - 70

3x = -69

x = -23

2). 0.2 = $\frac{6+2x}{12+x}$

0.2(12 + x) = 6 + 2x

2.4 + 0.2x = 6 + 2x

2.4 - 6 = 2x - 0.2x

1.8x = -3.6

x = -2

3). 0.8 = $\frac{x}{x+0.5}$

0.8(x + 0.5) = x

0.8x + 0.4 = x

x - 0.8x = 0.4

0.2x = 0.4

x = 2

4). 3.5 = $\frac{4+2x}{0.5-x}$

3.5(0.5 - x) = 4 + 2x

1.75 - 3.5x = 4 + 2x

-3.5x - 2x = 4 - 1.75

-5.5x = 2.25

x = - $\frac{2.25}{5.5}$

x = - $\frac{9}{22}$

Solve this equation please <br>5X2 - 15 = 5

Lena [83]

Answer:

x = 2 or x = -2

Step-by-step explanation:

5x² - 15 = 5

⇌

5x² = 15 + 5

⇌

5x² = 20

⇌

x² = 20/5 = 4

⇌

x² = 2²

⇌

x² - 2² = 0

⇌

(x - 2)(x + 2) = 0

⇌ we use the zero product property

x - 2 = 0 or x + 2 = 0

⇌

x = 2 or x = -2
