In the equation 3x plus 7 equals 13, x is equal to 2.
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
7.5
x = -11
19 (7 + 12 = 4x - 3x)
3x plus -5 equal 7. so x is 4 so 3times 4 is 12-5 will equal 7.
Ten. That means 3x equals 30, and 30 divided by three is ten.
If: 3x-7 = 5x+13 Then: x = -10
Well lets see: 2y = 6x+8 y=3x+4 does not equal y=3x+6 So they are not the same.
no
10x + 5 which is also equal to 5(2x + 1)
Both equations are equal and so: 3x+1 = 2x+3 3x-2x = 3-1 x = 2 and by substituting y = 7
