I can't seem to solve this for x correctly...I got 128 over 55 as an answer which can't be correct. Please help me find the correct answer! Thanks!
The equation is:
.05x-.6(x+2)=.08
Please show the work as well as the answer. Thanks again.
I got 1.12/.55
.05 x-.6x+1.2= .08
-.55x= -1.12
-1.12/-.55
That doesn't work because -.6 x 2= -1.2, not positive 1.2. And it still doesn't equal .08 when you plug it in.
1--.05x-.6(x+2)=.08
2--Multiplying by 100 yields
...5x - 60x - 120 = 8
3--Collecting terms, -55x = 128
4--Therefore x = -128/55
5--Checking:
...05(-128/55) - .6(-128/55 - 1.2 = .08
...Multiplying through by 55 yields
....05(-128) - .6(-128) - 66 = 4.4
6----6.4........+.76.8...-66..= 4.4
---------76.8 = 76.8
x = -128/55
To solve the equation, you need to follow these steps:
Step 1: Distribute the -0.6 to both terms in parentheses:
-0.6(x+2) = -0.6x - 1.2
Step 2: Rewrite the equation with the simplified expression:
0.05x - 0.6x - 1.2 = 0.08
Step 3: Combine like terms on the left side:
-0.55x - 1.2 = 0.08
Step 4: Add 1.2 to both sides to isolate the variable:
-0.55x = 0.08 + 1.2
Step 5: Simplify the right side of the equation:
-0.55x = 1.28
Step 6: Divide both sides by -0.55 to solve for x:
x = 1.28 / -0.55
Now, let's calculate the value of x:
x ≈ -2.327 (rounded to three decimal places)
So, the correct value of x is approximately -2.327.
