maksim [4K]

Answer:

X = 2

Y = 1

Step-by-step explanation:

x + 4y = 6

3x + 3y = 9

3x + 12y = 18

3x + 3y = 9

9y = 9

x + 4y = 6

y = 1

x + 4 * 1 = 6

y = 1

x + 4 = 6

y = 1

x = 2

so there ia only 1 solution for this equation is (2;1)

Done :))

3 - -97

3 + 97

100

Range is always positive

I want to know what g is

MAVERICK [17]

Answer:

Step-by-step explanation:

2(5-4g) + 3g - 11 = 5(g-3) - 12 - 3g (remove the parantheses)

10 - 8g + 3g - 11 = 5g - 15 - 12 -3g (Calculate and collect like terms)

-1 - 5g = 2g - 27 (move the terms)

-5g -2g = 27 + 1 (collect like terms and calculate)

-7g = -26 (divide both sides)

so G = 26/7

What is the best way to classify each equation? 22-3x+7x=4(x+5) ,6(2x-3=3(3-5), 6x-14=2(3x-7), 6x+3(x-4)=8(x-3)

Romashka-Z-Leto [24]

1. 22 - 3x + 7x = 4(x + 5)
 22 - 3x + 7x = 4x + 20
 +3x +3x +3x 
 22 + 10x = 7x + 20
 -7x -7x 
 22 + 3x = 20
 -22 -22
 3x = -2
 3 3
 x = -2/3

2. 6(2x - 3) = 3(3 - 5)
 12x - 18 = 3(-2)
 12x - 18 = -6
 +18 +18
 12x = 12
 12 12
 x = 1

3. 6x - 14 = 2(3x - 7)
 6x - 14 = -3x
 6x - 14 = 2(-7)
 6x - 14 = -14
 +14 +14
 6x = 0
 6 6
 x = 0

4. 6x + 3(x - 4) = 8(x - 3)
 6x + 3x - 12 = 8x - 24
 9x - 12 = 8x - 24
 -8x -8x 
 x - 12 = -24
 +12 +12
 x = -12
