David's last equation to solve is x/100+3/100=8/100. Write and solve an equivalent equation with easier numbers that would give

JulijaS [17]

$\sf\dfrac{x}{100}+\dfrac{3}{100}=\dfrac{8}{100}$

Subtract 3/100 to both sides:

$\sf\dfrac{x}{100}=\dfrac{5}{100}$

Cross multiply:

$\sf100x=500$

Divide 100 to both sides:

$\sf~x=5$

Or we could just multiply both sides of the equation by 100, to give us:

$\sf~x+3=8$

Subtract 3 to both sides:

$\sf~x=5$

Solve for x, worth 10 points

Anton [14]

Answer: x=22

Step-by-step explanation:

Since the angles are corresponding angles, use x+14=5x-74. You get 36=36 meaning it is right when you substitute the value for x.

x+14=5x-74

-x on both sides

14=4x-74

+74 on both sides

88=4x

Divide both sides by 4

x=22
