Answer:
x = 3
Step-by-step explanation:
29 - 3x = 5x + 5
You want to have the variable of x on one side of the equation, so add 3x to both sides.
29 = 8x + 5
You want to isolate the variable of x, so subtract 5 from both sides.
24 = 8x
You want the variable x on its own, so divide both sides by 8.
3 = x
Check your answer by plugging x back into the original equation.
29 - 3(3) = 5(3) + 5
Solve.
29 - 9 = 15 + 5
20 = 20
Your answer is correct!
A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
24x1/4
24/4
6... 25%=25/100=1/4
