Answer:
You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)
Step-by-step explanation:
Answer:
y = 40
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
y+10 + 2y +50 = 180
3y+60 = 180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide each side by 3
3y/3 = 120/3
y = 40
2x+9= 35
Move 9 to the other side
positive +9 changes to negative -9
2x+9-9= 35-9
2x= 26
Divide by 2 for 2x and 26
2x/2= 26/2
x= 13
Check answer by using substitution method
2x+9= 35
2(13)+9= 35
26+9= 35
35= 35
Answer : x= 13 ( first choice)
