x = 3/2
Step-by-step explanation:
Given equation is:
As we have to solve for x, x will be isolated on one side of the equation
So,
<u>1. Addition property of equality </u>
4x will be added on both sides
<u>2. Division property of Equality</u>
Dividing both sides by 6
Hence,
x = 3/2

We can get the answer to this equation by solving for the variable (r).
7.4 - 9 - 2r = 18
We want to get r on one side, so we want to push everything else to the other side.
-2r = 18 - 7.4 + 9
-2r = 19.6
2r = -19.6
r = -9.8

Answer:
£2.38
Step-by-step explanation:
Write and solve an equation of ratios:
£1.40 2.5 kg
----------- = ------------
c 4.25 kg
Cross multiplying, we get:
(£1.40)(4.25 kg) = (2.5 kg*c), or
(£1.40)(4.25 kg)
c = -------------------------- = £2.38
2.5 kg
