Question

7(х+6)=4(5х+4) 1/6(х+9)=-1/3

Answer 1

7(х+6)=4(5х+4)
7х+42=20х+16
7х-20х=16-42
-13х=-26
х=2

Answer 2

Let's solve these equations step by step:

1. 7(х+6)=4(5х+4)

First, we need to simplify both sides of the equation using the distributive property:

7x + 42 = 20x + 16

Next, we want to isolate the variable x on one side of the equation, so we need to subtract 7x from both sides and subtract 16 from both sides:

7x - 20x = 16 - 42

-13x = -26

Finally, we solve for x by dividing both sides by -13:

x = 2

2. 1/6(х+9)=-1/3

To solve this equation, we want to isolate the variable x on one side of the equation. First, we need to simplify the left side of the equation by multiplying both sides by 6:

(1/6)(x+9) * 6 = (-1/3) * 6

x + 9 = -2

Next, we want to isolate x, so we subtract 9 from both sides:

x = -11

Therefore, the solution to the second equation is x = -11.
