What is ur question exactly?
RS + ST = RT
(3x + 1) + (2x - 2) = 64
5x - 1 = 64
5x = 65
x = 13
Answer:
one solution (-2 ; 5)
Step-by-step explanation:
hello : 2x + 3y= 11
...(*)
-x-5y=-23.....(**)
by(**) : x= -5y+23
put this value into (*) : 2(-5y+23)+3y=11
-10y+46+3y=11
-7y = -35
y=5
but x= -5y+23
so : x= -5(5)+23 =-2
Answer:
4k+ 23
