X+1=10
move +1 to the other side
sign changes from +1 to -1
to get X by itself
X+1-1=10-1
X=10-1
Answer:
X=9
2x=y
×+y=36
x=Ed's age
y=His brothers age
Then you plug in Y into the secound equation.
×+2×=36.
You then add the two x together.
3x=36
The to get x by itself you take 36 and dive by 3 to get 12.
x=12
Then plug 12 into the equation
12+y=36
Then get y by itself.
y=24.
So, Ed's age is 12 and Ed's brother's age is 24.
Answer:
x = 1 3/22
Step-by-step explanation:
1/2 x + 3/5 x = 5/4
We need to get rid of the fractions by multiplying by 20 on each side
20 (1/2 x + 3/5 x) = 20 * 5/4
Distribute
10x + 12x = 25
Combine like terms
22x = 25
Divide each side by 22
22x/22 = 25/22
x = 22/22 + 3/22
x = 1 3/22
