7-3b = 5b+15 solve the equation

7-3b = 5b+15

move 5b to the other side

sign changes from +5b to -5b

7-3b-5b=5b-5b+15 ( combine like terms)

7-3b-5b=15

7-8b=15

move 7 to the other side

7-7-8b=15-7

-8b=15-7

-8b=8

divide both sides by -8

to get +b and by itself

-8b/-8=8/-8

b=-1

b=-1

Step-by-step explanation:

we have isolate variable on one side and number on other

so we move 5b to the right side and it becomes negative and we move 7 to the left and it becomes negative

-3b-5b=15-7          

-8b = 8

__      __   (you divided -8 by -8b to isolate b and by the other side)

-8        -8

b= -1

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
