Solve systems of equations for x + y, please!! 6x + 2y = 30 9x - 4y = 3

Vikentia [17]

Answer:

Step-by-step explanation:

6x + 2y = 30

9x - 4y = 3

if we double the first equation and add up to second one, we cancel 4y:

12x+9x=60+3 ⇒ 21x=63 ⇒ x=3

now we can find y:

6*3+2y=30 ⇒ 2y= 30- 18 ⇒ 2y= 12 ⇒ y=6

finally, x+y

x+y= 3+6= 9

Write the addition or subtraction shown by the number line

disa [49]

Start at 4.

So far you have: 4

Now you go 7 units left. Going left means a subtraction. Going 7 units left means subtracting 7.

So far you have: 4 - 7

The result is -3.

The subtraction is:

4 - 7 = -3

PLEASE HELP (100PTS)

Step2247 [10]

Answer:

x = 6

Step-by-step explanation:

• ∠THX and ∠XHV have a common side HX and a common vertex H

This means they are two adjacent angles.

Then

m∠THX + m∠XHV = m∠THV

Then

53 + 12x−9 = 16x + 20

Solving the equation:

53 + 12x−9 = 16x + 20

⇔ (53 − 9) + 12x = 16x + 20

⇔ 44 = 16x - 12x+ 20

⇔ 44 - 20 = 4x

⇔ 24 = 4x

$\Longleftrightarrow x = \frac{24}{4} =6$
