3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
5x+3 = -17 5x = -17-3 5x = -20 x = -4
-6x+3 = -7-5x 7+3 = 6x-5x 10=x
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33

If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
5x plus 3 does equal 3 plus 5x; commutative law.

5x+3=25 5x = 22 (subtract 3 from each side) x = 22/5 (divide both sides by 5)
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x + 3 = -12 5x =-12-3 =-15 x = -3
5x - 4x = 13 - 3 ie x = 10
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
-4x + 3 = -5x + 3add 5x to each sidex + 3 = 3subtract three from each sidex = 0
3 + 5x = 38 -> 5x = 35 -> x = 7
0. 6x + 3 = 5x + 141. 6x = 5x + 11 [subtracting 3]2. x = 11 [subtracting 5x]
