Can someone please show me how to do these problems? I've been trying but I'm having a hard time...

1.Simplify the expressions on each side of the equation to obtain an equivalent equation:

5x + 12 + 4x -16= 100/2

2.Angles UVW and angles XYZ are complementary angles. m of angle UVW is 18 degress less than m of angle XYZ. What is m of angle UVW?

3.After a 24% increase, the price of a tennis racquet was $37.82. What was it's original price?

Thanks so much!!

5x + 12 + 4x -16= 100/2

9x - 4 = 50

9x = 54

x = 6

3.

1.24x = 37.82

x = ?

let angle XYZ = x

then angle UVW = x-18

don't complemenatry angles add up to 90 ?

so x + x-18 = 90

solve for x, sub into x-18
