Sam's height is 15 centimeters less than 2 times Martha's height. If Sam is 185 centimeters tall, and Martha's height is x, the relationship between the heights can be represented by the equation 2x − 15 = 185. What is Martha's height?
Solve the equation to find out first, isolate the variable by adding 15 to both sides 2x - 15 = 185 +15 +15 ------- ------ 2x- 0 = 200 then simplify 2x= 200 then isolate the variable even more by dividing both sides by 2
