a + 3 = 2a + 2

move 2a to the other side

sign changes from +2a to -2a

a-2a+3= 2a-2a + 2

a-2a+3=2

-a+3=2

move 3 to the other side

-a+3-3= 2-3

-a= 2-3

-a= -1

mutiply both sides by -1 to get +a

(-1)(-a)=(-1)(-1)

Answer:

a= 1

pav-90 [236]

Answer:

38.5

Step-by-step explanation:

Lets say, first number = x

Second number = 3x+7

Total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 38.5

Hope this helps!!
