$\frac{x}{4}=2$

what would be my first step?

multiply both sides by 4

divide both sides by 4

add 4 to both sides

multiply both sides by 2

$\frac{18}{x}=2$

what would be my first step

add 2 to both sides

multiply x to both sides

divide by 18 to both sides

multiply 18to both sides

$\frac{40}{x}=5$

What would my next step look like? (select all that

40 = 5x

40x = 5

200 = x

multiply both sides by x

Simplify the Expression:

2x²- 7x + 10 - x²

-4x²+ 10

20x

x²- 7x + 10

3x²- 7x - 10

Solve the equation

5x - 14 = 8x + 4

x = 6

x = -6

x = -18/13

x = 10/3
