Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.

Solve the equation. −10x + 1 + 7x = 37

pantera1 [17]

−10x + 1 + 7x = 37

combine like terms

-3x + 1 = 37

subtract 1 from both sides

-3x = 36

divide both sides by (-3)

x = - 12

Answer

x = - 12

Margo can purchase tile at a store for $0.99 per tile and rent a tile saw for $18. At another store she can borrow the tile saw

Margarita [4]

(0.99x) + 18 = 1.19x

18 = 1.19x
- 0.99x

18 = 0.2x

18/0.2 = x

90 = x
(She must by 90 tiles for the cost at both stores to be the same, Cheers!)
