Given h (x) = 2x + 5, solve for x when h (x) = 3

Step-by-step explanation:

h(x)=2x+5

3=2x+5

3-5=2x

-2=2x

x= -2

2

x= -1

hope it help u

3 = 2x + 5

Collect like terms

3 - 5= 2x

-2 = 2x

x=-1

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
