1) Solve for x. 4x + 12x = 2,000 2) Solve for x. -4.6x - 8.4x = -132.6 3) Jak bought a cat for $210. It was 25% off. What was the original price? 4) Solve for x. 2.6x + 18x = 12x + 84 5) Solve for x. 8/3x + 4/3x = 2/3x + 10 6) Solve for x. 18x - 10x + 18 = 4x + 68 7) Chloe has $100 and saves $11 each week. Brian has $37 and saves $15.50 each week. How long till they have the same amount? 8) Solve for x. 8(x + 4) + 4x = 104 9) Solve for x. 16(2x + 3x + 2) = -8x + 296 10) Rue bought a book and a reader that was 30% off. The book was $12.40 and the total was $214.54. What was the original price of the reader? 11) How many solutions? x + 5.5 8 = 5x -13.5 - 4x 12) How many solutions? 6(1/3x + 2) = 8x + 12 - 2x 13) 12(1/3x + 2 - 1/4x) = 5x - 6 14) Fira's weight can be found by using the equation 4(x + 3) & Archi's by using 6(x + 1). x is the number of weeks. After how many weeks will they weigh the same? 15) How can you tell if an equation has no solution? 16) How can you tell if an equation has one solution? 17) How can you tell if an equation has infinite solution?
