Question

Решите уравнение : х + х +10+х-5=215 , так что бы получилось 70.СРОЧНО!

Answer 1

Х + х +10+х-5=215
3х=215-10+5
3х=210
х=70

Answer 2

X+x+10+x-5=215
3x+5=215
3x=210
X=70

Answer 3

Solving the Equation for x:

To solve the equation x + x + 10x - 5 = 215 such that the result is 70, we can follow these steps:

1. Combine like terms on the left side of the equation. 2. Solve for x.

Step 1: Combine Like Terms

Combining like terms on the left side of the equation gives us: x + x + 10x - 5 = 215 12x - 5 = 215

Step 2: Solve for x

To isolate x, we add 5 to both sides of the equation: 12x = 220

Then, we divide both sides by 12 to solve for x: x = 220 / 12 x = 18.3333

So, the value of x that satisfies the equation x + x + 10x - 5 = 215 and results in 70 is approximately 18.3333.
