Let's solve your equation step-by-step.
4x+2x−5=7x−1
Step 1: Simplify both sides of the equation.
4x+2x−5=7x−1
4x+2x+−5=7x+−1
(4x+2x)+(−5)=7x−1(Combine Like Terms)
6x+−5=7x−1
6x−5=7x−1
Step 2: Subtract 7x from both sides.
6x−5−7x=7x−1−7x
−x−5=−1
Step 3: Add 5 to both sides.
−x−5+5=−1+5
−x=4
Step 4: Divide both sides by -1.
−x

Answer:
48,24,30
Step-by-step explanation:
Let, the length of second side be x
A/c to question,
first side (a) = 2x
second side (b) = x
third side (c) = x + 6
Perimeter of ∆ (p) = 102
And,
Perimeter of ∆ = a + b + c
102 = 2x + x + x + 6
102 - 6 = 4x
96 = 4x
x = 96/4
x = 24
Now,
first side = 2*24 = 48
second side = 24
third side = 24 + 6 = 30

Answer:
The area of LQM is 
Step-by-step explanation:
Given
Area of PNQ = 8
Area of LPQ = 16
See attachment for triangles
The area of PNQ is calculated as:
Substitute 8 for Area
The area of LPQ is calculated as:
Substitute 16 for Area
From the attachment:
Make LP the subject
So:
We have:
and
Equate both expressions:
Divide both sides by PQ
Multiply both sides by 2
Since PNQ is similar to LNM, the following equivalent ratios exist:
Substitute
Area of LQM is:
This gives:
Recall that:
So:
