Suppose you are asked to solve the following system of equations by substitution. y = 2x + 5
3x + 2y = -4

B & C
A & D
B & E
( The choices in the picture )

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
