Lets pair them up into the same terms first.
3y + 2y = 5y
2 + 5 = 7
so,
3y + 2 + 2y + 5
= 5y + 7
Answer:
<u>Use cross-multiplication to solve these</u>
- 1) 6/2 = 4/p ⇒ 6p = 4*2 ⇒ p = 8/6 ⇒ p = 4/3
- 2) 4/k = 8/2 ⇒ 8k = 2*4 ⇒ k = 8/8 ⇒ k = 1
- 3) n/4 = 8/7 ⇒ n = 4*8/7 ⇒ n = 32/7
- 4) 5/3 = x/4 ⇒ x = 4*5/3 ⇒ x = 20/3
If you would like to solve the equation p + 1/4 = 2, you can calculate this using the following steps:
p + 1/4 = 2
p = 2 - 1/4
p = 8/4 - 1/4
p = 7/4 = 1 3/4
The correct result would be 1 3/4.
Let's check if (3 , 6) is the point of intersection of the given lines ~
and
If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.
So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
