Question

In 2-4, write yes or no to indicate whether the expressions are equivalent. Grade 6 math, please help

Answer 1

you have to combine like terms so -10x & 2x = -8x (same signs add & keep diff signs subtract, take the sign of the higher value then you’ll be exact) & -3 & -5 = -8 so it’s -8x -8 & then distribut the - 4 so (-4)(3x) = -12x & -4(-2) = 8. for 2. it’s no, -8x-8 & 12x+8 are no equivalent.
