Solve for .
2r +7= 16
r

Step-by-step explanation:

=> 2r + 7 = 16

=> 2r = 16 - 7

=> r = 9/2

=> r = 4.5

r= 1/2

Step-by-step explanation:

Subtract  7   from both sides of the equation

2 + 7 = 1 6

2 + 7 − 7 = 1 6 − 7

Simplify

2 = 1 6 − 7

Subtract  16r  from both sides of the equation

2 = 1 6 − 7

2 − 1 6 = 1 6 − 7 − 1 6

Simplify

-14r= -7

Divide both sides of the equation by the same term

− 1 4 = − 7

-14r=-7

− 1 4 − 1 4

Simplify

r= 1/2
