Answer:
The answer to your question is: x = - 14
Step-by-step explanation:
Solve 4 + x/7 = 2
Multiply by 7 7(4 + x/7 = 2)
expand 28 + x = 14
simplify x = 14 - 28
result x = - 14

Answer:
Shop A & $400
Step-by-step explanation:
-4.7 + 27.5 + 122.3 = $145.1 (Shop A)
-0. 2 + 14.5 + 130.4 = $144.7 (Shop B)
Difference = 145.1 - 144.7 = $0.4
0.4 × 1000 = $400
Answer:
It takes 2 hours and 45 minutes
<span>2x+4y=12
y=1/4x-3
can be re-written as
2x + 4y = 12 4y+2x = 12
4y= x - 12 or -4y -x = 12
------------------
Adding, we get x = 24.
</span>From the given equation y=1/4x-3 (better written as y = (1/4)x - 3), we
get y = (1/4)(24) - 3, or 6 - 3, or 3.
The solution is thus (24, 3).
Here I used the "addition-subtraction method" to solve this system of equations.
