x+2+x+5=3\left(x-2\right)-4
Multiply both sides of the equation by 2.
2x+2+5=3\left(x-2\right)-4
Combine x and x to get 2x.
2x+7=3\left(x-2\right)-4
Add 2 and 5 to get 7.
2x+7=3x-6-4
Use the distributive property to multiply 3 by x-2.
2x+7=3x-10
Subtract 4 from -6 to get -10.
2x+7-3x=-10
Subtract 3x from both sides.
-x+7=-10
Combine 2x and -3x to get -x.
-x=-10-7
Subtract 7 from both sides.
-x=-17
Subtract 7 from -10 to get -17.
x=17
Multiply both sides by -1.
