Answer:
Since the above triangle is Iscocleles we can make our equation-
5x - 8 = 2x + 7
5x - 2x = 8 + 7
3x = 15
x = 5
Hope it helps
Answer:
300/1500, 1/5, or 20%

Answer:
Y=2
X=-1
Step-by-step explanation:
In substitution method we have to put the value of one variable from first equation to the another given equation.
here equation are
x=3y-7 ......a
4x+3y=2 .......b
put the value of x from equation first into the second equation
so, 4(3y-7)+3y=2
(12y-28)+3y=2
15y-28=2
15y=2+28
15y=30
or y=30/2=2
now put this y value in equation a
x=3(2)-7
x=6-7=-1
hence y=2 and x= -1
