4 x +1.7 x=3
помогите пожалуйста
Simplifying0.7(x + 4) + 1.7(x + -3) = 0Reorder the terms:0.7(4 + x) + 1.7(x + -3) = 0(4 * 0.7 + x * 0.7) + 1.7(x + -3) = 0(2.8 + 0.7x) + 1.7(x + -3) = 0Reorder the terms:2.8 + 0.7x + 1.7(-3 + x) = 02.8 + 0.7x + (-3 * 1.7 + x * 1.7) = 02.8 + 0.7x + (-5.1 + 1.7x) = 0Reorder the terms:2.8 + -5.1 + 0.7x + 1.7x = 0Combine like terms: 2.8 + -5.1 = -2.3-2.3 + 0.7x + 1.7x = 0Combine like terms: 0.7x + 1.7x = 2.4x-2.3 + 2.4x = 0Solving-2.3 + 2.4x = 0Solving for variable x.Move all terms containing x to the left, all other terms to the right.Add 2.3 to each side of the equation.-2.3 + 2.3 + 2.4x = 0 + 2.3Combine like terms: -2.3 + 2.3 = 0.00.0 + 2.4x = 0 + 2.32.4x = 0 + 2.3
