Question

1)4b+2b-40=20; 2)(250-x):2=100 ​

Answer 1

Відповідь:

1)10

2)50

Покрокове пояснення:

1) 4в+2в-40=20

6в=20+40

6в=60

в=10

2)(250-х)/2=100

250-х=100*2

250-х=200

-х=200-250

-х=-50

х=50

Answer 2

Sure, I'd be happy to help you solve these equations!

Equation 1:
4b + 2b - 40 = 20

Combine the like terms on the left side: 6b - 40 = 20

Now, isolate the variable 'b': 6b = 20 + 40 6b = 60

Divide both sides by 6: b = 60 / 6 b = 10

So, the solution for Equation 1 is b = 10.

Equation 2:
(250 - x) / 2 = 100

Multiply both sides by 2 to eliminate the fraction: 250 - x = 200

Now, isolate the variable 'x': x = 250 - 200 x = 50

The solution for Equation 2 is x = 50.
