4x - 7 = -15 4x = -8 x = -2
x=2 1/7
x = 13
When X = 4, 15X = 15 * X = 15 * 4 = 60
If: 4x = x+15 Then: x = 5
2
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
15
4x - 7 = -15 4x = -8 x = -2
15
2 x 15
2 x 1.5 = 3three2 x 1.5 = 3
x=2 1/7
(-5, 2)
When c = -3 then 4c + 5c - 2 = [4 x -3] + [5 x -3] - 2 = -12 +(-15) - 2 = -12 -15 -2 = -29
Move the numerals to the right hand side: x = 15 - 7 - 2 ie x = 6
