10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5

35x^2 + 77x + 42 Improved answer: 5x+67x+7 When simplified = 72x+7

If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3

-6x+3 = -7-5x 7+3 = 6x-5x 10=x

3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.

35x^2 + 77x + 42

It is: y = -1/5x+7 that is perpendicular to y = 5x+7

5x + 7 = 4subtract 7 from both sides5x = -3divide both sides by 5x = -3/5

3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
