Question

890-X=210×2 Х×70=1000-650​

Answer 1

X=210*2=420=890-420
X=470
—————————
470+420=890

X=1000-650=350:70
X=5
————————
70*5=350

Answer 2

Первое 470
Второе 5 …..

Answer 3

Let's solve the equations step by step.

Equation 1: 890 - X = 210 × 2

To solve for X, we'll first simplify the right side of the equation: 210 × 2 = 420

Now we can substitute this value back into the equation: 890 - X = 420

To isolate X, we'll move the constant term to the other side: X = 890 - 420

Calculating the right side: X = 470

So, the solution for X in the first equation is X = 470.

Equation 2: X × 70 = 1000 - 650

To solve for X, we'll simplify the right side of the equation: 1000 - 650 = 350

Now we can substitute this value back into the equation: X × 70 = 350

To isolate X, we'll divide both sides of the equation by 70: X = 350 / 70

Calculating the right side: X = 5

Therefore, the solution for X in the second equation is X = 5.

In summary, the solutions for the given equations are: X = 470 for the first equation, and X = 5 for the second equation.
