Answer:
65x
Step-by-step explanation:
Observe que estos son terminos similares... por lo que podemos simplemente sumarlos y restarlos. Entonces obtenemos:
25x + 12x + 31x - 8x + 5x
= 37x + 31x - 8x + 5x
= 68x - 8x + 5x
= 60x + 5x
= 65x

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+2=−15
Step 3: Subtract 2 from both sides.

x=−17
Step 4: Multiply both sides by 8.
