distribute the -5 on the left side and the -6 on the right
8-10x-5=2-6x+18
combine like terms on each side
3-10x = 20-6x
add 10x to both sides
3=20+4x
subtract 20 from both sides
-17 = 4x
divide both sides by 4
-17/4 = x

8-5(2x+1)=2-6(x-3)
8-10x-5 = 2- 6x +18
-10x + 3 = -6x + 20
-4x = 17
x = -17/4

First you distribute the number in front of the parenthesis by multiplying -5 by (2X+1) and -6 by (X-3).
This is what you get:
8-10X-5=2-6X+18
combine like terms by subtracting 8 and 5 on one side and adding 2 and 18 on the other side. You get:
3-10X=20-6X
now you want to get the X's on one side of the equation and all the numbers on the other side. In our example we will put the X's on the left and numbers on the right. To do this, since you have a positive 3 on one side, to get it to the other side you subtract it. You get:
-10X=17-6X Now you want to get the X's on the left side. since you have a -6X on one side, to get it to the other side you add. You get: -4X=17 Now you want to get X by itself so you have to divide both sides by -4. You get: X = -4.75

multiply it out
8 - 10x - 5 = 2 - 6x + 18
simplify
3 - 10x = 20 - 6x
add 10x to both sides
3 = 20 + 4x
subtract 20 from both sides
-17 = 4x
divide by 4
-17/4 or -4.25 = x

-3(4-t)=5-(t+a million) Symplifying 3t-12=5-t-a million Transposing the words 3t+t=12+5-a million 4t=sixteen t=4 Checking numerically -3(4-4)=5-(4+a million) -3(0)=5-4-a million 0=0 Their may be a contradiction if there have been a branch by way of 0. that's not the case, the left term is a multiplication by way of 0.

I won't tell u the answer, I'm a SEVENTH grader and i can solve this.
U use the distributive property on both sides
Then combine like terms
VOILA! u solved a math problem
