10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
-6x-6 -or- -6(x+1)
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
6 + x - 10x = 11 - 4x 6 - 9x = 11 - 4x add 9x to both sides: 6 = 11 + 5x subtract 11 from both sides: -5 = 5x divide both sides by 5: -1 = x
-31 - 10x = 41 - 4x In algebra what you do to one side of the equation you do the the same as the other First add 31 to both sides -10x = 72 -4x then add 4x to both sides -6x = 72 divide both sides by -6 x = -12

10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
It is: -4x-10x = -14x
-6x-6 -or- -6(x+1)
-31 - 10x = 41 - 4x-31 + 31 - 10x = 41 + 31 - 4x- 10x = 72 - 4x-10x + 4x = 72 - 4x + 4x-6x = 72-6x ÷ -6 = 72 ÷ -6x = -12Check Your Solution:x = -12-31 - 10x = 41 - 4x-31 - 10(-12) = 41 - 4(-12)-31 + 120 = 41 + 48120 - 31 = 41 + 4889 = 41 + 4889 = 89

10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
It is 2(2x+3) when factorised
6 + x - 10x = 11 - 4x 6 - 9x = 11 - 4x add 9x to both sides: 6 = 11 + 5x subtract 11 from both sides: -5 = 5x divide both sides by 5: -1 = x
-31 - 10x = 41 - 4x In algebra what you do to one side of the equation you do the the same as the other First add 31 to both sides -10x = 72 -4x then add 4x to both sides -6x = 72 divide both sides by -6 x = -12
x=5. 10x-4x (6x) +10-6x (=10) If 10 is 2x, x=5.
4x-6 = -6x-4 4x+6x = 6-4 10x = 2 x = 2/10 x = 1/5 Regards, A Pakistani!
