Circle the linear equations in one variable in the answer space.

Here's a detailed breakdown for question 2. 2. Bulatkan persamaan linear dalam satu pemboleh ubah pada ruang jawapan. Circle the linear equations in one variable in the answer space. A linear equation in one variable must meet two criteria: 1. It contains only one type of variable. 2. The highest power of that variable is 1. Let's check each expression: 10 - 7x = -0.5: This has one variable (x) with a power of 1. ✅ 5 + (2w)/(3) = 1: This has one variable (w) with a power of 1. ✅ (1)/(2r) - 3 = r: This can be written as (1)/(2)r^-1 - 3 = r. Since r has a power of -1, it is not linear. ❌ 4g + g^2 = 2: This has one variable (g), but the highest power is 2 (g^2), so it is not linear. ❌ y + 4 = x: This has two different variables (y and x), so it is not a linear equation in one* variable. ❌ 6 + 4b = 2: This has one variable (b) with a power of 1. ✅ 1 - b^2 = b: This has one variable (b), but the highest power is 2 (b^2), so it is not linear. ❌ 2t - 3 = s: This has two different variables (t and s), so it is not a linear equation in one* variable. ❌ 4h - 2 = -3h: This has one variable (h) with a power of 1. ✅ 4 - vw = 6: This has two different variables (v and w) and they are multiplied (vw), which means it is not linear. ❌ The linear equations in one variable to be circled are: 10 - 7x = -0.5 5 + (2w)/(3) = 1 6 + 4b = 2 4h - 2 = -3h What's next?
