X+ y = 10
2x = 2y+4
2x/2 = 2/2y+4/2
x = y + 2
x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4
x + y =10
x + 4 =10
x +4-4 =10-4
x = 6
Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12
7/12 and 1/2
Get the common denominator
Multiply 1/2 by 6
7/12 and 6/12
Hello.
In order to solve this equation, we need to isolate the variable (in this case, the variable is x)
The first step is to use the Distributive Property and distribute 3:


Now, add 3 to both sides:



Now, subtract 2x from both sides:


Therefore, the answer is

I hope it helps.
Have a nice day.
