Solve the inequality just like you would solve an equation
<span>3x - 12 > 15
add 12 to both sides
3x > 27
divide both sides by 3
x > 9
Or read as "the solution to </span><span>3x - 12 > 15 is x is greater than 9"
Hope this helps :)</span>
Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13
Answer:
3/5=x
Step-by-step explanation:
3÷x=5
multiply both sides by x
x(3÷x)=(5)x
cancel out x on the left side of the equation
3=5x
divide both sides by 5
3/5=(5x)/5
cancel out 5 on the right side
3/5=x
This expression is equivalent (9+3)4
