4s + 5 = 19
First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5.
Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14.
Third, divide both sides by 4. / Your problem should look like: s =

.
Fourth, simplify

to

. / Your problem should look like: s =

which is the answer.

Answer:
x=3/2y−6
y=2/3x+4
Step-by-step explanation:
Let's solve for y.
12=−2x+3y
Step 1: Flip the equation.
−2x+3y=12
Step 2: Add 2x to both sides.
−2x+3y+2x=12+2x
3y=2x+12
Step 3: Divide both sides by 3.
3y/3=2x+12/3
