Question

-7(0,3x-8)+2(0,4x+5)=8

Answer 1

-2,1x+56+0,8x+10=8
-1,3x+66=8
-1,3x=8-66
-1,3x=-58
x=-58/-1,3
x=44,61

Answer 2

To solve the equation -7(0,3x-8) + 2(0,4x+5) = 8, we need to find the value of x that satisfies the equation.

Step 1: Distribute the coefficients: -7 * 0 + (-7) * (3x) + (-7) * (-8) + 2 * 0 + 2 * (4x) + 2 * 5 = 8

Step 2: Simplify the equation: 0 - 21x + 56 + 0 + 8x + 10 = 8

Step 3: Combine like terms: -21x + 8x + 56 + 10 = 8

Step 4: Continue simplifying: -13x + 66 = 8

Step 5: Isolate x on one side of the equation: -13x = 8 - 66 -13x = -58

Step 6: Solve for x: x = -58 / -13 x = 4.46153846154 (rounded to 11 decimal places)

Therefore, the solution to the equation is x ≈ 4.46.
