Solve for x -62=-15(x-1)+4

vovangra [49]

Answer:

$x=4\frac{11}{15}$

Step-by-step explanation:

- 62 = - 15(x - 1) + 4

- 52 = - 15x + 15 + 4

- 52 = - 15x + 19

- 52 - 19 = - 15x + 19 - 19

- 71 = - 15x

- 15x ÷ - 15 = - 71 ÷ - 15

$x = \frac{71}{15}$

$x=4\frac{11}{15}$

Solve for x= 7x + 15 = 38

777dan777 [17]

In order to solve for x in the equation 7x + 15 = 38, you must first subtract 15 from both sides.
7x + 15 = 38
7x + 15 - 15 = 38 - 15
7x = 23
Then you must divide so there is only 1x = a number. This can be done by dividing both sides by 7.
7x = 23
7x / 7 = 23 / 7
x ≈ 3.286
So the solution for x in the equation 7x + 15 = 38 is x ≈ 3.286.
Hope this helps!
