Question

What is the measure of the 5x+25

Answer 1

As you can see:

RM+MT = RT

Where:

RM = 5x + 9

MT = 8x - 6

RT = 198

Replacing the data:

5x + 9 + 8x - 6 = 198

Add like terms:

(5x + 8x) + (9 - 6) = 198

13x + 3 = 198

Solve for x:

Subtract 3 from both sides:

13x + 3 - 3 = 198 - 3

13x = 195

Divide both sides by 13:

13x/13 = 195/13

x = 15
