Ответ:
x = 22.5
Step-by-step explanation:
Step 1: Write equation
2.4(x - 10) = 8 + 1.2x - 5
Step 2: Solve for x
Distribute 2.4: 2.4x - 24 = 8 + 1.2x - 5Combine like terms: 2.4x - 24 = 1.2x + 3Subtract 1.2x on both sides: 1.2x - 24 = 3Add 24 to both sides: 1.2x = 27Divide both sides by 1.2: x = 22.5Step 3: Check
Plug in x to verify it's a solution.
2.4(22.5 - 10) = 8 + 1.2(22.5) - 5
2.4(12.5) = 8 + 27 - 5
30 = 8 + 22
30 = 30
