3(x-4)= 2(x + 5) <br> Find the number
ohaa [14]

Answer:

x=22

Step-by-step explanation:

Reorder the terms:

3(-4 + x) = 2(x + 5)

(-4 * 3 + x * 3) = 2(x + 5)

(-12 + 3x) = 2(x + 5)

Reorder the terms:

-12 + 3x = 2(5 + x)

-12 + 3x = (5 * 2 + x * 2)

-12 + 3x = (10 + 2x)

Solving

-12 + 3x = 10 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-12 + 3x + -2x = 10 + 2x + -2x

Combine like terms: 3x + -2x = 1x

-12 + 1x = 10 + 2x + -2x

Combine like terms: 2x + -2x = 0

-12 + 1x = 10 + 0

-12 + 1x = 10

Add '12' to each side of the equation.

-12 + 12 + 1x = 10 + 12

Combine like terms: -12 + 12 = 0

0 + 1x = 10 + 12

1x = 10 + 12

Combine like terms: 10 + 12 = 22

1x = 22

Divide each side by '1'.

x = 22

Simplifying

x = 22

Can somebody help me please .

Answer:

The graph of the equation is given below.

Step-by-step explanation:

We are given the equation, -3x-4y=4

On simplifying, we get,

-3x-4y=4 i.e. 4y=-3x-4

So, the table is given by,

x                       4y=-3x-4                                       y

-4                     4y=-3\times (-4)-4 i.e. 4y=8             2

0                      4y=-3\times (0)-4 i.e. 4y=-4            -1

4                      4y=-3\times 4-4 i.e. 4y=-16             -4

Thus, the graph of the equation is given below.
