Can someone answer and explain thank you I’ll mark brainliest

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

What is sin 7x/4 ? i need on this urgent trig
