Answer:
x=23
Step-by-step explanation:
1. Move variable (3x) to the left-hand side and change its sign
Move constant (7) to right-hand side and change its sign
x-7=3x-53
x-3x-7=-53+7
2. Collect like terms [x-3x]
Calculate the sum [-53+7]
x-3x= -53+7
-2x= -46
3. Divide both sides of the equation by -2
-2x/2 =-46/2
4. Solution
x=23
