x=\frac{9}{43}
Alternative Form
x\approx 0.209302
Evaluate
7x-9=-2x\times 18
Multiply the terms
7x-9=-36x
Move the variable to the left side
7x-9+36x=0
Add the terms
More Steps
Evaluate
7x+36x
Collect like terms by calculating the sum or difference of their coefficients
\left(7+36\right)x
Add the numbers
43x
43x-9=0
Move the constant to the right side
43x=0+9
Removing 0 doesn't change the value,so remove it from the expression
43x=9
Divide both sides
\frac{43x}{43}=\frac{9}{43}
Solution
x=\frac{9}{43}
Alternative Form
x\approx 0.209302
