If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
What does 2x plus 7 plus 5x-4-x equal?
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
What is the answer to 10x plus 7 equals 5x plus 32?
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
What is 10x plus 7 equals 5x plus 22?
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
What is the value of f of x plus 7 if f of x equals -5x-9?
Let, f (x) = - 5x - 9 Therefore, f(x) + 7 = - 5x - 9 + 7 f(x) + 7 = - 5x - 2
If x equals 7 and y equals 2x plus 3 what is 5x plus y?
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
5x plus 3 equals -17?
5x+3 = -17 5x = -17-3 5x = -20 x = -4
What does 2x plus 7 plus 5x-4-x equal?
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
