I need the answer for the question -4(x-10)+8 for my homework please.

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
