4) 6(2x+3) - 7(3x - 4)= 12x + 18 - 21x + 28= (12 - 21)x + 18 + 28= -9x + 46
5) 4(3x+7) - 6(2x+5)= 12x + 28 - 12x - 30= 0x - 2= -2
6) 6(x-4)+2,3 = 3(2x-7) -8= 6x - 24 + 2,3 = 6x - 21 - 8= 6x - 21,7 = 6x - 29Since both sides of the equation are equal, the solution is no solution.
4) 6(2x+3) - 7(3x - 4)
= 12x + 18 - 21x + 28
= (12 - 21)x + 18 + 28
= -9x + 46
5) 4(3x+7) - 6(2x+5)
= 12x + 28 - 12x - 30
= 0x - 2
= -2
6) 6(x-4)+2,3 = 3(2x-7) -8
= 6x - 24 + 2,3 = 6x - 21 - 8
= 6x - 21,7 = 6x - 29
Since both sides of the equation are equal, the solution is no solution.
