Question

А÷15=54÷18= 800-х=870-610= у+420=600-56= 55×х=820-710 300-х=42×2

Answer 1

Answer 2

Let's solve each equation step by step:

1. А ÷ 15 = 54 ÷ 18 To find the value of A, simplify both sides of the equation: A / 15 = 54 / 18 A / 15 = 3 Now, multiply both sides of the equation by 15 to solve for A: A = 3 * 15 A = 45

2. 800 - x = 870 - 610 Simplify both sides of the equation: 800 - x = 260 Now, subtract 800 from both sides to solve for x: -x = 260 - 800 -x = -540 Divide both sides by -1 to get the value of x: x = 540

3. у + 420 = 600 - 56 Simplify both sides of the equation: у + 420 = 544 Now, subtract 420 from both sides to solve for у: у = 544 - 420 у = 124

4. 55 × x = 820 - 710 Simplify both sides of the equation: 55x = 110 Now, divide both sides by 55 to solve for x: x = 110 / 55 x = 2

5. 300 - x = 42 × 2 Simplify both sides of the equation: 300 - x = 84 Now, subtract 300 from both sides to solve for x: -x = 84 - 300 -x = -216 Divide both sides by -1 to get the value of x: x = 216

So, the solutions are: A = 45 x = 540 у = 124 x = 2 x = 216
