Question

Make x the subject of the formula y = 7 x + 4

Answer 1

Answer:

$x= \frac{y-4}{7}$

Step-by-step explanation:

$y=7x+4$

Subtract 4 from both sides.

$y-4=7x+4-4$

$y-4=7x$

Divide by 7 on both sides.

$\frac{y-4}{7} =7x/7$

$x= \frac{y-4}{7}$

Answer 2

Answer:

x = (y+4) / 7

Step-by-step explanation:

7x+4 = y

7x = y+4

x = (y+4) / 7

Hope this helps.

Good Luck
