Though i passed my GCSE Maths in 2008, i think i know the answer. See my method below:
8x+ 14= -10
Add 10 to both sides to get rid of the -10. This leaves you with;
8x+ 28= 0
You can guess that x needs to be a negative number that you can multiply by 8 to get -28.
7x8= 28, so -7x8=-28
Therefore;
x=-7
Interesting but unfortunately wrong, 8x-7 =-56 (maybe I'm wrong though I did my A-levels over 20 years ago)
8x + 14 = -10
8x = -10 - 14
8x = -24
x = -24/8
x = -3

What is 6x plus 3 equals 8x plus 14?
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
2y equals 8x - 14 4y equals 8x plus 4?
x=4, y=9 (4,9)
What is 8x-17 equals 6x plus 11?
8x-17=6x+112x=28x=14
6x equals 8x plus 28?
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
What is the answer to 6x plus 13 equals -57-8x?
10
8x plus 10 equals 4x plus 14?
8x + 10 = 3x +145x = 4x = 4/5 = 0.8Improved answer:8x+10 = 4x+148x-4x = 14-104x = 4x = 1
What is 6x plus 3 equals 8x plus 14?
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
WHAT IS -8x-10 plus -20 equals?
-8x - 10 - 20 = -8x - 30
6x plus 3 8x plus 14?
6x plus 3 equals to 8x plus 14 would lead to x = - 5.5.
How do you solve 8x plus -2 equals 10?
8x + -2 = 10 8x = 12 x = 1.5
2y equals 8x - 14 4y equals 8x plus 4?
x=4, y=9 (4,9)
What is 8x-17 equals 6x plus 11?
8x-17=6x+112x=28x=14
6x equals 8x plus 28?
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
What is the answer to 6x plus 13 equals -57-8x?
10
8x plus 2 equals 6x plus 10?
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
Y-8x plus 9y equals?
Y-8x plus 9y equals 10y-8x.
X plus 8y equals 22 -8x-2y plus 10?
8x + 64y = 176 Add: 62y = 186 so y = 3 and x = -2 This assumes you mean "equals 10", not "plus 10"
