Answer:

x=-96

Step-by-step explanation:

isolate x by moving -124x to the other side by adding -124x to -126x = -2x

then it will look like: 102= -2x-90

add 90 to both sides: 192= -2x

divide both sides by -2 to isolate x

x= -96

x = 96


-124x+126x = -90-102

2x = -90-102

2x = -192
divide both sides by 2

x = -96 !!
