Question

40-5×(3х-7)+4×(х+17)=0

Answer 1

40 - 5 * (3х - 7) + 4 * (х + 17) = 0
40 - (5*3х - 5*7) + (4х + 17 * 4) = 0
40 - 15х + 35 + 4х + 68 = 0
40 + 35 + 68 = 0 + 15х - 4х
143 = 11х
х = 143 : 11
х = 13
Ответ: х = 13

Answer 2

Ответ:

Пошаговое объяснение:

40 - 5 * (3х - 7) + 4 * (х + 17) = 0  

40 - (5*3х - 5*7) + (4х + 17 * 4) = 0

40 - 15х + 35 + 4х + 68 = 0  

40 + 35 + 68 = 0 + 15х - 4х

143 = 11х

х = 143 : 11

х = 13

40 - 5 * (3х - 7) + 4 * (x + 17) = 0

Answer 3

To solve the equation, let's simplify and then solve for the value of x:

40 - 5 × (3x - 7) + 4 × (x + 17) = 0

First, apply the distributive property and simplify:

40 - 15x + 35 + 4x + 68 = 0

Combine like terms:

(40 + 35 + 68) - (15x - 4x) = 0

143 - 11x = 0

Now, isolate x by moving the constant term to the other side of the equation:

-11x = -143

Finally, solve for x by dividing both sides by -11:

x = -143 / -11

x = 13

So, the solution to the equation is x = 13.
