Help please I don’t understand this at all & been stuck here for a hour

ELEN [110]

Answer:

Step-by-step explanation:

4b + 8 = 20

Subtract 8 from both sides

4b + 8 - 8 = 20 - 8

4b = 12

Now divide both sides by 4

4b/4 = 12/4

b = 3

Check:

LHS = 4b + 8

= 4*3 + 8

= 12 + 8

= 20 = RHS

Write the equation 5x − 2y = 10 in the form y = mx + b. y equals start fraction five over two end fraction x minus 10 y equals s

vaieri [72.5K]

Answer:

y = 5/2x - 5

Step-by-step explanation:

You have to rearrange the equation so that it is equal to y.

5x - 2y = 10

(5x - 2y) - 5x = -5x + 10

-2y = -5x + 10

(-2y)/-2 = (-5x)/-2 + (10)/-2

y = 5/2x - 5
