Just take it slow and easy, one small step at a time:

Write the problem :        <u>4x + 2 = 7x - 8</u>

Add  8  to each side:      4x + 10 = 7x

Subtract  4x  from each side:  10 = 3x

Divide each side by  3 :          10/3 = x

That wasn't so bad, was it ?

The measure of two complementary angles have a ratio of 3:2. What is the measure of the larger angle?
azamat

Answer:

54 degrees

Step-by-step explanation:

Complementary angles add to 90 degrees

3:2

Multiply each by x

3x:2x

Add the angles together and set equal to 90

3x+2x = 90

Combine like terms

5x= 90

Divide each side by 5

5x/5 = 90/x

x =18

The angles are 3x = 3(18) =54

   and 2x = 2(18) = 36
