Answer:
n=10
Step-by-step explanation:
first distribute
-3 + 1/2 n = -1/2n + 7
next multiply both sides of the quation by 2
-6+n=-n+14
add n to both sides
-6+n+n=14
add 6 to both sides
n+n=14+6
combine like terms
2n=20
divide both sides by 2
n=10

Step-by-step explanation:
solve . 15 - 10x = 5(x + 9) show your work
Answer:
x= -2
Step-by-step explanation:
Let's solve your equation step-by-step.
15−10x=5(x+9)
Step 1: Simplify both sides of the equation.
15−10x=5(x+9)
15+−10x=(5)(x)+(5)(9)(Distribute)
15+−10x=5x+45
−10x+15=5x+45
Step 2: Subtract 5x from both sides.
−10x+15−5x=5x+45−5x
−15x+15=45
Step 3: Subtract 15 from both sides.
−15x+15−15=45−15
−15x=30
Step 4: Divide both sides by -15.
−15x/-15 = 30/ -15
x= −2
