The isosceles triangle has a perimeter of 7.5 m. which equation can be used to find the value of x if the shortest side, y, measures 2.1 m? 2x – 2.1 = 7.5 4.2 + y = 7.5 y – 4.2 = 7.5 2.1 + 2x = 7.5

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
