This one is elementary. :) First, you want to precise both words interior a similar bases(it is 2 for this reason). 2^(3x+2)=8^(-2x+a million) will change into 2^(3x+2)=2^3(-2x+a million) because 8 = 2^3 because the bases are equivalent, you could say that the exponents are equivalent as well. for this reason, you've 3x + 2 = 3(-2x + a million) then you definitely purely ought to scrub up for x. 3x + 2 = -6x + 3 9x = a million x = a million/9 << answer :)

Verified answer
4(x - 1) + 2 = 3x + 8 - 2x
4x - 4 + 2 = x + 8
4x - 2 = x + 8
3x - 2 = 8
3x = 10
x = 10/3
X=-10

4x-4+2=3x+8-2x
4x-2=x+8
4x-x=8+2
3x=10
x=10/3
x=3.33 or 3 1/3
Solve for x:
4(x-1)+2=3x+8-2x
Distribute[4(x-1)]:
4x-4+2=3x+8-2x
Combine Like Terms[3x and -2x]:
4x-4+2=x+8
Combine Like Terms[-4 and 2]:
4x-2=x+8
Subtract either "x" or "4x" to both sides. I'll pick "x":
3x-2=8
Add 2 to both sides:
3x=10
Divide 3 to both sides:
So x is:
x=3.33(repeating)
OR in fraction form:
x=10/3
4x-4+2 = 3x + 8 - 2x
4x - 3x + 2x = 8 - 2 + 4
3x = 10
x = 10/3
distribute
4x-4+2=3x+8-2x
combine like terms
4x-2=x+8
get x's to one side, constants to other by subtraction and addition
3x=10
divide both sides by 3
x=10/3 = 3 and 1/3
check your answer:
plug in to original equation
4[(10/3)-1]+2=3(10/3)+8-2(10/3)
4(7/3)+2=10+8-20/3
34/3=30/3+24/3-20/3(true)
to solve for x:
1) repeating problem: 4(x - 1) + 2 = 3x + 8 - 2x
2) multiply left side by 4 = distribute the 4, and on the right side combine the x's: 4x - 4 + 2 = x + 8
3) add the -4 and +2 on the left side: 4x - 2 = x + 8
4) subtract the x (from the right side) from both sides and add 2 (opposite of -2) to both sides: 3x = 10
5) divide by 3 on both sides to get x by itself: x = (10/3)
x= 10/3
4x - 4 + 2 = 3x + 8 - 2x
4x - 2 = 8 + x
3x = 10
x = 3.3 repeating
