2\left(x+2\right)\geq 7\left(x-3\right)
Multiply both sides of the equation by 14, the least common multiple of 7,2. Since 14 is positive, the inequality direction remains the same.
2x+4\geq 7\left(x-3\right)
Use the distributive property to multiply 2 by x+2.
2x+4\geq 7x-21
Use the distributive property to multiply 7 by x-3.
2x+4-7x\geq -21
Subtract 7x from both sides.
-5x+4\geq -21
Combine 2x and -7x to get -5x.
-5x\geq -21-4
Subtract 4 from both sides.
-5x\geq -25
Subtract 4 from -21 to get -25.
x\leq \frac{-25}{-5}
Divide both sides by -5. Since -5 is negative, the inequality direction is changed.
x\leq 5
Divide -25 by -5 to get 5.
