Solve the equation $$ 6x+4=-2 $$.
Solve the equation by following steps:
- step0: Solve for $$x$$:
  $$6x+4=-2$$
- step1: Move the constant to the right side:
  $$6x=-2-4$$
- step2: Subtract the numbers:
  $$6x=-6$$
- step3: Divide both sides:
  $$\frac{6x}{6}=\frac{-6}{6}$$
- step4: Divide the numbers:
  $$x=-1$$
Solve the equation $$ 5=4a-3 $$.
Solve the equation by following steps:
- step0: Solve for $$a$$:
  $$5=4a-3$$
- step1: Swap the sides:
  $$4a-3=5$$
- step2: Move the constant to the right side:
  $$4a=5+3$$
- step3: Add the numbers:
  $$4a=8$$
- step4: Divide both sides:
  $$\frac{4a}{4}=\frac{8}{4}$$
- step5: Divide the numbers:
  $$a=2$$
Solve the equation $$ 2.2s-0.9=3.5 $$.
Solve the equation by following steps:
- step0: Solve for $$s$$:
  $$2.2s-0.9=3.5$$
- step1: Move the constant to the right side:
  $$2.2s=3.5+0.9$$
- step2: Add the numbers:
  $$2.2s=4.4$$
- step3: Divide both sides:
  $$\frac{2.2s}{2.2}=\frac{4.4}{2.2}$$
- step4: Divide the numbers:
  $$s=2$$
The solutions to the equations are:
a. $$ x = -1 $$
b. $$ a = 2 $$
c. $$ s = 2 $$
a. $$ x = -1 $$ b. $$ a = 2 $$ c. $$ s = 2 $$
