Rewrite each problem so that x appears on only one side

x = -5/21

Step-by-step explanation:

Step 1: Write equation

2(12x - 1) = (21x - 49)/7

Step 2: Solve for x

Multiply both sides by 7: 14(12x - 1) = 21x - 49Distribute 14: 168x - 14 = 21x - 49Subtract 21x on both sides: 147x - 14 = -49Add 14 to both sides: 147x = -35Divide both sides by 147: x = -5/21

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
