Which expression is equivalent to 8t - 18 – 20t + 14?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

It is 5.8 you add all of the up to equat 180 then solve the equation
