Answer:
x = 4.2
Step-by-step explanation:
Simplifying
18.6 + -2x = 3x + -2.4
Reorder the terms:
18.6 + -2x = -2.4 + 3x
Solving
18.6 + -2x = -2.4 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
18.6 + -2x + -3x = -2.4 + 3x + -3x
Combine like terms: -2x + -3x = -5x
18.6 + -5x = -2.4 + 3x + -3x
Combine like terms: 3x + -3x = 0
18.6 + -5x = -2.4 + 0
18.6 + -5x = -2.4
Add '-18.6' to each side of the equation.
18.6 + -18.6 + -5x = -2.4 + -18.6
Combine like terms: 18.6 + -18.6 = 0.0
0.0 + -5x = -2.4 + -18.6
-5x = -2.4 + -18.6
Combine like terms: -2.4 + -18.6 = -21
-5x = -21
Divide each side by '-5'.
x = 4.2
Simplifying
x = 4.2

Ooh, these are fun
if 2 are in a row, then we have the 3rd number, easy
you got number 1, 2, 3, 4 right I th ink
5.
7+?+10=24
17+?=24
?=7
that middle right blank is 7
now
8+7+?=24
15+?=24
?=9
middle left blank is 9
we can also find the diagonal (bottom left to top right0
?+8+7=24
?=9
bottom left is 9
we now can do bottom row
9+?+10=24
19+?=24
5=?
bottom middle is 5
now go vertical, left most
9+9+?=24
18+?=24
?=6
top left is 6
finally, 6+?+7=24
13+?=24
?=11
top middl is 11
6.
middle left
?+10+5=30
15+?=30
?=15
middle left is 15
now left row
9+15+?=30
24+?=30
?=6
bottom left=6
diagonals
topl left to bottom right
9+10+?=30
19+?=30
?=11
bottom left=11
bottom row
6+?+11=30
17+?=30
?=13
bottom middle=13
middle collumn
?+10+13=20
?+26=30
?=4
top middle=4
top row
9+4+?=30
13+?=30
?=17
top right=17
