Answer:
x = 1 and y = 6
Step-by-step explanation:
3x - 2y = -9 ........................... eqn 1
4x + 3y = 22 ........................... eqn 2
to eleminate y, multiply eqn 1 by 3 and eqn 2 by 2
(3x - 2y = -9) × 3
(4x + 3y = 22) × 2
9x - 6y = -27 ........................... eqn 3
8x + 6y = 44 ........................... eqn 4
Add eqn 3 and 4 together and we get
17x = 17
x = 17/17
x = 1
To get y, substitute 1 for x in any of the eqns
taking eqn 4
8(1) + 6y = 44
8 + 6y = 44
6y = 44 - 8
6y = 36
y = 36/6
y = 6
Answer:
it can fly 6 miles in 10 mins as 10×6=60 36/6=6
Answer:
-7 = m
Step-by-step explanation:
5m − 7 = 6m
Subtract 5m from each side
5m-5m − 7 = 6m-5m
-7 = m
It’s x>1
Step-by-step
|3x+2|>3
step 1: add 2 both sides
|3x +2|-2+2>3+2
|3x+2|=5
step 2: solve absolute value
|3x+2|>2
we know either 3x+2> 3x+2<-5
3x+2>5 subtract two from both sides
3x+2-2>5-2
3x>3
Now divide three by both sides
X>1
