Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=
7
8
x−15
2+x=
7
8
x+−15
x+2=
7
8
x−15
Step 2: Subtract 7/8x from both sides.
x+2−

x)=(8)*(−17)
Answer:
1.05
Step-by-step explanation:
number starts as .105
slide the decimal over 1 space
1.05
The number is 15,
I really don’t know if there’s such a strategy to find this out, I just used trial & error:
(a*4)+(a*3)=35
(5*4)+(5*3)=35
20+15=35
.6578 this would be the answer
