Question

(3,7х+6,25)×7,2=111,6

Answer 1

26,64x+45=111,6

26,64×=66,6

x=66,6÷26,64

x=2,5

Answer 2

Let's solve the equation step by step:

(3 * 7x + 6.25) * 7.2 = 111.6

First, let's simplify the expression inside the parentheses:

21x + 6.25

Now, the equation becomes:

(21x + 6.25) * 7.2 = 111.6

Next, distribute the 7.2 to both terms inside the parentheses:

151.2x + 45 = 111.6

Now, let's isolate the variable x. First, subtract 45 from both sides of the equation:

151.2x = 111.6 - 45 151.2x = 66.6

Finally, divide both sides by 151.2 to find the value of x:

x = 66.6 / 151.2 x ≈ 0.44048

So, the value of x that satisfies the equation is approximately 0.44048.
