3m-7=8 solve please NEED HELP

Answers

1.) add 7 to both sides

3m = 8 + 7

2.) add 8+7

3m = 15

3.) divide both sides by 3

m = 15/3

4.) divide 15/3

5.) m = 5

Solve for m.

Add 7 to both sides to get 3m=15

Then divide by sides by 3 to get m=5.

The final answer is m=5.

Answer:

Option B

Option C

Step-by-step explanation:

$x^(2) +2x=4$

we need to divide the coefficient of x by half since it is required for completing square, this term is added and subtracted at the same time to keep the equation intact, so we have

$x^(2) +2x+1-1=4$

later we have

$(x+1)^(2) -1=4$

$(x+1)^(2)= 4+1$

$(x+1)^(2) = 5$

$\sqrt{(x+1)^(2)} =√(5)$

we know

$\sqrt[2]{a^(2)} = abs (a)$

$abs(x+1)=√(5)$

we have

$x+1=√(5)$

$x+1= -√(5)$

so we have

$x=√(5)-1$

$x=-√(5)-1$

finally

$x=+- √(5)-1$

The second is obtained by summing the two given equations

f(x)=8x-10

g(x)=3x+5

-----------------

f(x)+g(x)=11x-5
