3x + x + 10 + x = 5x + 10
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
If: 3x-7 = 5x+13 Then: x = -10
122-5x = 3x+10 122-10 = 3x+5x 112 = 8x 112/8 = x x = 14
3x - 5x + x = -x
3x + x + 10 + x = 5x + 10
5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.
If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
If: 3x-7 = 5x+13 Then: x = -10
122-5x = 3x+10 122-10 = 3x+5x 112 = 8x 112/8 = x x = 14
3x2 + 5x + 2 is a quadratic expression that can be factored as follows: 3x2 + 5x + 2 = 3x2 + 3x + 2x + 2 = 3x(x + 1) + 2(x + 1) = (3x + 2)(x + 1)
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
