I need help with my last homework question. What is 11v-220 is greater than or equal to 2 (5-3v)-6v?
if it is equal will be11v-220=2(5-3v)-6v11v-220=10–6v-6v11v+6v+6v=10+22023v=23023v:23=230:23v=10Now let’s see if it’s right11v-220=2(5–3v)-6v11*10–220=2(5–3*10)-6*10110–220=10–30–60-110=-80 So it’s not equal but greater
