Answer:
question n.3 is a
Step-by-step explanation:
y=3x/2 + 4
2y= 2·3x/2 + 2·4
2y= 3x+8
2y-3x=8
Step-by-step explanation:
x+3y=-4(eqn1)
x=-4-3y
from (eqn 2)
2(-4-3y)+6y=5
-8-6y+6y=5
y=5+8=13.
y=13
from eqn 1
x+3(13)=-4
x+39=-4
x=-4-39
x=-43.
Answer:
-3x= 2×2-4
Step-by-step explanation:
-3x= 4-4
-3x= 0
divide both sides by the co-efficient of x
-3x/-3= 0÷-3
x = 0
The sum (addition) of t and 2 is equal to (=) 5 less than (subtraction) t
2 + t = t - 5
