Question

(2.61 -4х) /0,03 + 4.6 =90

Answer 1

(2.61-4х):0.03+4.6=90

(2.61-4х):0.3=90-4.6

(2.61-4х):0.03=85.4

2.61-4х=2.562

-4х=2.562-2.61

-4х=-0.048

х=-0.048:(-4)

х=0.012

ОТВЕТ:0.012

Answer 2

(2,61-4х):0,03+4,6=90

(2,61-4х):0,03=90-4,6

(2,61-4х):0,03=85,4

2,61-4х=85,4*0,03

2,61-4х=2,562

-4х=2,562-2,61

-4х=-0,048

х=-0,048:(-4)

х=0,012

Answer 3

Alright, let's solve this equation step by step.

(2.61 - 4x) / 0.03 + 4.6 = 90

First, let's isolate the fraction on one side:

(2.61 - 4x) / 0.03 = 90 - 4.6

Now, subtract 4.6 from 90:

(2.61 - 4x) / 0.03 = 85.4

Next, multiply both sides by 0.03 to get rid of the fraction:

2.61 - 4x = 85.4 * 0.03

2.61 - 4x = 2.562

Now, isolate the term with x by subtracting 2.61 from both sides:

-4x = 2.562 - 2.61

-4x = -0.048

Finally, divide by -4 to solve for x:

x = -0.048 / -4

x = 0.012

So, the solution to the equation is x = 0.012.
