X + x - x is x
y + y + y is 3y
-z + z - z is -z
x + 3y
Step-by-step explanation:
Given: 2x-6=5x+18
step 2 : the subtraction property of equality
step 4: the addition propert of equality
step 5: the division propert of equality
X - the number
3(x+1)=2x+4
3x+3=2x+4
3x-2x=4-3
x=1
Distribute 2 and remove parentheses :
1/2x+8=3x-6
Multiply both sides of equation by 2:
x+16=6x-12
Move terms:
x+16-6x=-12
x-6x=-12-16
Collect like terms:
-5x=-28
Divide both sides:
x=28/5
