-104=-2(1+7x)-4 answer​

Mathematics
1 answer:
SCORPION-xisa [38]3 years ago
5 0

Add 4 to both sides

-104 + 4 = -2(1 + 7x)

Simplify -104 + 4 to -100

-100 = -2(1 + 7x)

Divide both sides by -2

-100/-2 = 1 + 7x

Two negatives make a positive

100/2 = 1 + 7x

Simplify 100/2 to 50

50 = 1 + 7x

Subtract 1 from both sides

50 - 1 = 7x

Simplify 50 - 1 to 49

49 = 7x

Divide both sides by 7

49/7 = x

Simplify 49/7 to 7

Switch sides

<u>Answer: x = 7</u>
