Question
Solve the equation
x=723
Alternative Form
x=3.2˙85714˙
Evaluate
19−15(x−2)=26−8x
Move the expression to the left side
19−15(x−2)−(26−8x)=0
Subtract the terms
More Steps
Evaluate
19−15(x−2)−(26−8x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
19−15(x−2)−26+8x
Subtract the numbers
−7−15(x−2)+8x
−7−15(x−2)+8x=0
Calculate the sum or difference
More Steps
Evaluate
−7−15(x−2)+8x
Expand the expression
More Steps
Calculate
−15(x−2)
Apply the distributive property
−15x−(−15×2)
Multiply the numbers
−15x−(−30)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−15x+30
−7−15x+30+8x
Add the numbers
23−15x+8x
Add the terms
More Steps
Evaluate
−15x+8x
Collect like terms by calculating the sum or difference of their coefficients
(−15+8)x
Add the numbers
−7x
23−7x
23−7x=0
Move the constant to the right-hand side and change its sign
−7x=0−23
Removing 0 doesn't change the value,so remove it from the expression
−7x=−23
Change the signs on both sides of the equation
7x=23
Divide both sides
77x=723
Solution
x=723
