Solve for x: 0.2(2x-1)=0.2+0.08
a.1.4
b.5
c.2
d.0.3

A

Step-by-step explanation:

0.4x-0.2=0.28

0.4x=.28+0.2

0.4x=0.48

step-by-step explanation:

first, eliminate the parenthesis:

x

+

second, group like terms:

x

−

4

x

+

2

third, combine like terms:

(

)

x

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
