4x + 20
Impossible to give a correct solution in the absence of any plus or minus signs.
Yes.
This would simplify as 4x-5
x = 0,1
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
The lines are perpendicular.
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
4x + 20
minus 1
x - 2
Impossible to give a correct solution in the absence of any plus or minus signs.
Yes.
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
This would simplify as 4x-5
8x + 15
