10. Solve for y. 3y + 6p = 9r

What are “like terms”? why can we only add like terms?

What additional information could be used to prove abc =mqr using sas? check all that apply.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
