Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−x+3+x−5−x=x+10
Step 1: Simplify both sides of the equation.
3x−x+3+x−5−x=x+10
3x+−x+3+x+−5+−x=x+10
(3x+−x+x+−x)+(3+−5)=x+10(Combine Like Terms)
2x+−2=x+10
2x−2=x+10
Step 2: Subtract x from both sides.
2x−2−x=x+10−x
x−2=10
Step 3: Add 2 to both sides.
x−2+2=10+2
x=12
East= 45 x 22 = 990 students
west= 42 x 23 = 996 students
996 - 990 = 6 students
990 - 996 = -6 students
There are 6 more students at West school than East school. There are -6 more students at East school than West school.
Hope it helps!
4y=7x
The sum of the numbers is 22
so, x+y=22
x=(22-y)
by substitute (22-y) for x in the first equation.
66 multiplied by 2 so your answer is 132
