Question

3,12:2,7+1,9х=2х+1,5

Answer 1

Ответ: 3,12:2,7+1,9х=2х+1,5⇒156/135+1,9*х=2*х+1,5⇒1 7/45+1,9*х=2*х+1,5⇒0,1*Х=1 7/45-1,5=1 14/90-1 45/90=(14-45)/90=-31/90⇒х=-310/90=-3 4/9.

Answer 2

Let's solve the given equation step by step:

3,12:2,7 + 1,9х = 2х + 1,5

Step 1: Simplify the left side of the equation by performing the division first. 3.12 ÷ 2.7 ≈ 1.15555556

The equation becomes: 1.156 + 1.9х = 2х + 1.5

Step 2: Move all terms containing 'x' to one side of the equation and constants to the other side. 1.9х - 2х = 1.5 - 1.156

Step 3: Combine like terms on both sides. (1.9 - 2)х = 0.344

Step 4: Solve for 'x': -0.1х = 0.344

Step 5: Divide both sides by -0.1 to isolate 'x': x ≈ 0.344 / -0.1

Step 6: Calculate the value of 'x': x ≈ -3.44

So, the value of 'x' that satisfies the equation is approximately -3.44.
