Answer:
x=14
Step-by-step explanation:
2 times x = 2x and 2 time 9 is 18 so the equation is 2x-18=10. then you add 18 to both sides and get 2x=28 then simplify to x=14
2(x-9)=10
Step one - Simplify both sides
(2)(x)+(2)(-9)=10 (distribute)
2x+-18=10
2x-18=10
Step two - Add 18 to both sides
2x-18+18=10+18
2x=28
Step three - Divide both sides by 2
2x÷2 = 28÷2
x= 14
