4x + 15 = 6x + -11

Reorder the terms:
15 + 4x = 6x + -11

Reorder the terms:
15 + 4x = -11 + 6x

Solving
15 + 4x = -11 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
15 + 4x + -6x = -11 + 6x + -6x

Combine like terms: 4x + -6x = -2x
15 + -2x = -11 + 6x + -6x

Combine like terms: 6x + -6x = 0
15 + -2x = -11 + 0
15 + -2x = -11

Add '-15' to each side of the equation.
15 + -15 + -2x = -11 + -15

Combine like terms: 15 + -15 = 0
0 + -2x = -11 + -15
-2x = -11 + -15

Combine like terms: -11 + -15 = -26
-2x = -26

Divide each side by '-2'.
x = 13

Simplifying
x = 13

X= 13 because you have to add the x all to the left side than minus eleven from both sides which would equal -2x=-26 then divide by -2 which would equal x=13

Soloha48 [4]
<span>First figure out how many people there are all together. So mrs and mr is 2 there three children so 2+3=5 so next round 179 to 200 and multiply 200x5. To do that you can use the mental math way witch would be to take the whole number out of 200 and make it 2. Then take the 5 in 200x5 and multiply 2x5. Then add the 2 zeros there were. And your estamated answer would be 1,000.
2+3=5
179=200
200x5
2x5=10
1,000
To figure out your real answer you will have to take 179 and multiply it by 5 so it will look like this:
 34
179
x
   5
895
Soto conculde the answer would be:

Estamated: $1,000

Exact: $895

Hope this helps!</span>

Answer:

ΔLMN ≅ ΔLQP by (SAA)

Step-by-step explanation:

It is given that line (NM) is congruent to the line (PQ), meaning they have the same measure. This is signified by the small red line on each of these sides.

Moreover, it is also given that angle (MNL) is congruent to angle (QPL), this is shown by the red arc around these angles.

Finally one can figure out that angle (NLM) is congruent to angle (PLQ) by the vertical angles theorem. The verticle angles theorem states that when two lines intersect, the opposite angles are congruent.

Thus the two triangles are congruent by side-angle-angle postulate, abbreviated as (SAA).
