What is -7+4m+10=15-2m=

Mathematics
1 answer:
Inessa [10]2 years ago
5 0

Answer:

m=2

Step-by-step explanation:

Add the numbers

-7+4m+10=15-2m

3+4m=15-2m

Rearrange terms

3+4m=15-2m

4m+3=15-2m

Rearrange terms

4m+3=15-2m

4m+3=-2m+15

Subtract 3 from both sides of the equation

4m+3=-2m+15

4m+3-3=-2m+15-3

Simplify

4m=-2m+12

Add 2m to both sides of the equation

4m=-2m+12

4m+2m=-2m+12+2m

Simplify

6m=12

Divide both sides of the equation by the same term

6m = 12

6m/6 = 12/6

Simplify

m = 2

Solve y
Ksivusya [100]

The value of y in -3 = 7\left(y-\dfrac97\right) is 6/7

<h3>How to solve for y?</h3>

The equation is given as:

-3 = 7\left(y-\dfrac97\right)

Open the bracket

-3 = 7y - 9

Add 9 to both sides of the equation

7y = 6

Divide both sides by 7

y= 6/7

Hence, the value of y in -3 = 7\left(y-\dfrac97\right) is 6/7

___ cosb =1/2 sin(a+b)+sin(a-b)?
vodomira [7]

Answer:

That would be sina.

Step-by-step explanation:

sin(a+b) = sinacosb + cosasinb

sin(a-b) = sinacosb -  cosasinb

Adding we get  sin(a+b) + sin(a-b) = 2sinaccosb

so sinacosb = 1/2sin(a+b) + sin(a-b)
