I believe the first one is c
First, simplify. Combine like terms
10x - 3x = 7x
7x + 1 = x + 4
Isolate the x. Subtract x from both sides, and 1 from both sides
7x (-x) + 1 (-1) = x (-x) + 4 (-1)
7x - x = 4 - 1
Simplify
6x = 3
Isolate the x. Divide 6 from both sides
6x/6 = 3/6
x = 1/2
1/2, or 0.5 is your answer for x.
hope this helps
If you want to convert a fraction to a decimal, divide the top by the bottom. Fractions are basically glorified division.
1/2 = 0.5
And you can convert this to a percent by moving the decimal two places to the right. And change it to a % sign.
0.5 => 50%
