What is the answer to this equation? (picture attached)
SashulF [63]

Answer:

x = \frac{42}{5}

Step-by-step explanation:

Given

19 - \frac{5x+6}{4} = 7 ( subtract 19 from both sides )

- \frac{5x+6}{4} = - 12

Multiply both sides by - 4 to clear the fraction and the negative signs

5x + 6 = 48 ( subtract 6 from both sides )

5x = 42 ( divide both sides by 5 )

x = \frac{42}{5}
