Question

1) 17(1,6 - 5x) = 2,38 2) 10,2x – 7,4x + 0,88 = 2

Answer 1

1) 17(1,6 - 5x) = 2.38

   27,2 - 85x = 2,38

   -85x = 2,38 - 27,2

   -85x = -24,82

    x = 0,292

2) 10,2x - 7,4x + 0,88 = 2

   2,8x = 2 - 0,88

   2,8x = 1,12

   x = 0,4

 

Answer 2

It looks like you have provided two equations with variables. You want to solve for the values of the variables that satisfy these equations. Let's solve each equation step by step:

Equation 1: $17(1.6 - 5x) = 2.38$

Distribute the 17 on the left side: $17 \cdot 1.6 - 17 \cdot 5x = 2.38$

Simplify the left side: $27.2 - 85x = 2.38$

Now, isolate the variable $x$: $27.2 - 2.38 = 85x$ $24.82 = 85x$

Divide both sides by 85: $x = \frac{24.82}{85} \approx 0.2914$

Equation 2: $10.2x - 7.4x + 0.88 = 2$

Combine like terms on the left side: $2.8x + 0.88 = 2$

Subtract 0.88 from both sides: $2.8x = 2 - 0.88$ $2.8x = 1.12$

Now, isolate the variable $x$: $x = \frac{1.12}{2.8} \approx 0.4$

So, the solutions for the equations are approximately:

1. $x \approx 0.2914$
2. $x \approx 0.4$
