Two hours and thirty minutes if that's the question
Answer:
none
Step-by-step explanation:
to solve this equation we would say that
let
x + y = 5 .............................. equation 1
x + y = 6 .................................... equation 2
from equation 2
x + y = 6 .................................... equation 2
x = 6 -y...................................... equation 3
substitute for x into equation 1
x + y = 5 .............................. equation 1
6 - y + y = 5
from here this equation cannot be solved further therefore it has no solution.
A: 208cm
B: 27cm
C: 30,000cm
Hope this helps!
Answer:
2x + y = -4
Step-by-step explanation:
standard form of equation of straight line is
ax+by = c
that is terms containing x and y should be on LHS and constant term should be on RHS
______________________________________________
Given equation
y + 1 = - 2x - 3
lets bring -2x on LHS ,
add 2x on lHS and RHS
y + 1 + 2x = - 2x - 3 + 2x
=> y + 1 + 2x = -3
on lHS, 1 is there which constant term lets bring it on RHS
subtract 1 from both sides
y + 1 + 2x - 1= -3 -1
y + 2x = -4
rearranging it
2x + y = -4 (Answer)
