What is the correct first step to solve this system of equations. 4x-3y=-10, 2x+3y=4

a) add the 2 equations together
b) subtract the 2 equations
c) multiply the second equation by 3
d) divide the first equation by 4

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

how many friends does he have? i think some of the information got cut off in the problem.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
