Solve for X:
−71+43x=81x+143
To solve the equation −71+43x=81x+143, we complete the following steps:
Step 1: Isolate the terms involving x on one side of the equation and the constant terms on the other side.
Start by subtracting 81x from both sides:
−71+43x−81x=143
Step 2: Move the constant term −71 to the other side:
43x−81x=143+71
Step 3: Find a common denominator for combining like terms.
For the left side, convert the fractions with denominators 4 and 8 to a common denominator of 8:
43x=86x
So, 86x−81x=85x
Now consider the right side by converting the fractions with denominators 14 and 7 to a common denominator of 14:
71=142
Therefore, 143+142=145
Step 4: Equate the simplified terms:
85x=145
Step 5: Solve for x by isolating it using multiplication:
Multiply both sides by 58 to clear the fractional coefficient of x:
x=145×58
Simplify this expression:
x=14×55×8=148
Therefore, the solution to the equation is x=148.
