Answer:

X=5/2

Step-by-step explanation:

1. subtract x from both sides, you now have 3x - 1/2 = 7

2. now you add 1/2 to both sides to get x by itself and you are left with 3x=7

4. divide by 3 on both sides to get x by itself

5. x=5/2

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

I believe this question should be from an I-Ready test. The answer would be $20.00. Because 70% of 20.00 is 14
